PIC24HJXXXGPX06A/X08A/X10A 2.0 GUIDELINES FOR GETTING STARTED WITH 16-BIT MICROCONTROLLERS Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F/PIC24H Family Reference Manual". Please see the Microchip web site (www.microchip.com) for the latest dsPIC33F/PIC24H Family Reference Manual sections. 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 2.1 Basic Connection Requirements Getting started with the PIC24HJXXXGPX06A/X08A/X10A family of 16-bit Microcontrollers (MCUs) requires attention to a minimal set of device pin connections before proceeding with development. The following is a list of pin names, which must always be connected: * All VDD and VSS pins (see Section 2.2 "Decoupling Capacitors") * All AVDD and AVSS pins (regardless if ADC module is not used) (see Section 2.2 "Decoupling Capacitors") * VCAP (see Section 2.3 "CPU Logic Filter Capacitor Connection (VCAP)") * MCLR pin (see Section 2.4 "Master Clear (MCLR) Pin") * PGECx/PGEDx pins used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes (see Section 2.5 "ICSP Pins") * OSC1 and OSC2 pins when external oscillator source is used (see Section 2.6 "External Oscillator Pins") 2.2 Decoupling Capacitors The use of decoupling capacitors on every pair of power supply pins, such as VDD, VSS, AVDD and AVSS is required. Consider the following criteria when using decoupling capacitors: * Value and type of capacitor: Recommendation of 0.1 F (100 nF), 10-20V. This capacitor should be a low-ESR and have resonance frequency in the range of 20 MHz and higher. It is recommended that ceramic capacitors be used. * Placement on the printed circuit board: The decoupling capacitors should be placed as close to the pins as possible. It is recommended to place the capacitors on the same side of the board as the device. If space is constricted, the capacitor can be placed on another layer on the PCB using a via; however, ensure that the trace length from the pin to the capacitor is within one-quarter inch (6 mm) in length. * Handling high frequency noise: If the board is experiencing high frequency noise, upward of tens of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor. The value of the second capacitor can be in the range of 0.01 F to 0.001 F. Place this second capacitor next to the primary decoupling capacitor. In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the power and ground pins as possible. For example, 0.1 F in parallel with 0.001 F. * Maximizing performance: On the board layout from the power supply circuit, run the power and return traces to the decoupling capacitors first, and then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally important is to keep the trace length between the capacitor and the power pins to a minimum thereby reducing PCB track inductance. Additionally, the following pins may be required: * VREF+/VREF- pins used when external voltage reference for ADC module is implemented Note: The AVDD and AVSS pins must be connected independent of the ADC voltage reference source. 2009-2012 Microchip Technology Inc. DS70592D-page 19 PIC24HJXXXGPX06A/X08A/X10A FIGURE 2-1: RECOMMENDED MINIMUM CONNECTION 0.1 F Ceramic 10 F Tantalum R R1 VSS VDD 2.4 VCAP VDD * Device Reset * Device programming and debugging C PIC24H VSS VDD VSS VDD AVSS VDD AVDD VSS 0.1 F Ceramic 0.1 F Ceramic 0.1 F Ceramic L1(1) Note 1: As an option, instead of a hard-wired connection, an inductor (L1) can be substituted between VDD and AVDD to improve ADC noise rejection. The inductor impedance should be less than 1 and the inductor capacity greater than 10 mA. Where: F CNV f = ------------2 1 f = ---------------------- 2 LC Master Clear (MCLR) Pin The MCLR pin provides for two specific device functions: MCLR 0.1 F Ceramic The placement of this capacitor should be close to the VCAP. It is recommended that the trace length not exceed one-quarter inch (6 mm). Refer to Section 21.2 "On-Chip Voltage Regulator" for details. (i.e., ADC conversion rate/2) During device programming and debugging, the resistance and capacitance that can be added to the pin must be considered. Device programmers and debuggers drive the MCLR pin. Consequently, specific voltage levels (VIH and VIL) and fast signal transitions must not be adversely affected. Therefore, specific values of R and C will need to be adjusted based on the application and PCB requirements. For example, as shown in Figure 2-2, it is recommended that the capacitor C, be isolated from the MCLR pin during programming and debugging operations. Place the components shown in Figure 2-2 within one-quarter inch (6 mm) from the MCLR pin. FIGURE 2-2: EXAMPLE OF MCLR PIN CONNECTIONS VDD 2 1 L = ---------------------- 2f C R(1) R1(2) 2.2.1 TANK CAPACITORS On boards with power traces running longer than six inches in length, it is suggested to use a tank capacitor for integrated circuits including MCUs to supply a local power source. The value of the tank capacitor should be determined based on the trace resistance that connects the power supply source to the device, and the maximum current drawn by the device in the application. In other words, select the tank capacitor so that it meets the acceptable voltage sag at the device. Typical values range from 4.7 F to 47 F. 2.3 CPU Logic Filter Capacitor Connection (VCAP) JP MCLR PIC24H C Note 1: R 10 k is recommended. A suggested starting value is 10 k. Ensure that the MCLR pin VIH and VIL specifications are met. 2: R1 470 will limit any current flowing into MCLR from the external capacitor C, in the event of MCLR pin breakdown, due to Electrostatic Discharge (ESD) or Electrical Overstress (EOS). Ensure that the MCLR pin VIH and VIL specifications are met. A low-ESR (< 5 Ohms) capacitor is required on the VCAP pin, which is used to stabilize the voltage regulator output voltage. The VCAP pin must not be connected to VDD, and must have a capacitor between 4.7 F and 10 F, 16V connected to ground. The type can be ceramic or tantalum. Refer to Section 24.0 "Electrical Characteristics" for additional information. DS70592D-page 20 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 2.5 ICSP Pins The PGECx and PGEDx pins are used for In-Circuit Serial ProgrammingTM (ICSPTM) and debugging purposes. It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. If the ICSP connector is expected to experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of Ohms, not to exceed 100 Ohms. Pull-up resistors, series diodes, and capacitors on the PGECx and PGEDx pins are not recommended as they will interfere with the programmer/debugger communications to the device. If such discrete components are an application requirement, they should be removed from the circuit during programming and debugging. Alternatively, refer to the AC/DC characteristics and timing requirements information in the "dsPIC33F/PIC24H Flash Programming Specification" (DS70152) for information on capacitive loading limits and pin input voltage high (VIH) and input low (VIL) requirements. Ensure that the "Communication Channel Select" (i.e., PGECx/PGEDx pins) programmed into the device matches the physical connections for the ICSP to MPLAB(R) ICD 3 or MPLAB REAL ICETM. For more information on ICD 3 and REAL ICE connection requirements, refer to the following documents that are available on the Microchip web site. * "Using MPLAB(R) ICD 3 In-Circuit Debugger" (poster) DS51765 * "MPLAB(R) ICD 3 Design Advisory" DS51764 * "MPLAB(R) REAL ICETM In-Circuit Emulator User's Guide" DS51616 * "Using MPLAB(R) REAL ICETM" (poster) DS51749 2009-2012 Microchip Technology Inc. 2.6 External Oscillator Pins Many MCUs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator (refer to Section 9.0 "Oscillator Configuration" for details). The oscillator circuit should be placed on the same side of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The load capacitors should be placed next to the oscillator itself, on the same side of the board. Use a grounded copper pour around the oscillator circuit to isolate them from surrounding circuits. The grounded copper pour should be routed directly to the MCU ground. Do not run any signal traces or power traces inside the ground pour. Also, if using a two-sided board, avoid any traces on the other side of the board where the crystal is placed. A suggested layout is shown in Figure 2-3. FIGURE 2-3: SUGGESTED PLACEMENT OF THE OSCILLATOR CIRCUIT Main Oscillator 13 Guard Ring 14 15 Guard Trace Secondary Oscillator 16 17 18 19 20 DS70592D-page 21 PIC24HJXXXGPX06A/X08A/X10A 2.7 Oscillator Value Conditions on Device Start-up If the PLL of the target device is enabled and configured for the device start-up oscillator, the maximum oscillator source frequency must be limited to 8 MHz for start-up with PLL enabled to comply with device PLL start-up conditions. This means that if the external oscillator frequency is outside this range, the application must start-up in the FRC mode first. The default PLL settings after a POR with an oscillator frequency outside this range will violate the device operating speed. Once the device powers up, the application firmware can initialize the PLL SFRs, CLKDIV and PLLDBF to a suitable value, and then perform a clock switch to the Oscillator + PLL clock source. Note that clock switching must be enabled in the device Configuration word. 2.8 Configuration of Analog and Digital Pins During ICSP Operations If MPLAB ICD 3 or REAL ICE is selected as a debugger, it automatically initializes all of the A/D input pins (ANx) as "digital" pins, by setting all bits in the AD1PCFGL register. The bits in this register that correspond to the A/D pins that are initialized by MPLAB ICD 3 or REAL ICE, must not be cleared by the user application firmware; otherwise, communication errors will result between the debugger and the device. If your application needs to use certain A/D pins as analog input pins during the debug session, the user application must clear the corresponding bits in the AD1PCFGL register during initialization of the ADC module. When MPLAB ICD 3 or REAL ICE is used as a programmer, the user application firmware must correctly configure the AD1PCFGL register. Automatic initialization of this register is only done during debugger operation. Failure to correctly configure the register(s) will result in all A/D pins being recognized as analog input pins, resulting in the port value being read as a logic `0', which may affect user application functionality. 2.9 Unused I/Os Unused I/O pins should be configured as outputs and driven to a logic-low state. Alternatively, connect a 1k to 10k resistor between VSS and the unused pins. DS70592D-page 22 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 3.0 CPU Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 2. "CPU" (DS70204) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The PIC24HJXXXGPX06A/X08A/X10A CPU module has a 16-bit (data) modified Harvard architecture with an enhanced instruction set and addressing modes. The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. The actual amount of program memory implemented varies by device. A single-cycle instruction prefetch mechanism is used to help maintain throughput and provides predictable execution. All instructions execute in a single cycle, with the exception of instructions that change the program flow, the double word move (MOV.D) instruction and the table instructions. Overhead-free, single-cycle program loop constructs are supported using the REPEAT instruction, which is interruptible at any point. 3.1 Data Addressing Overview The data space can be linearly addressed as 32K words or 64 Kbytes using an Address Generation Unit (AGU). The upper 32 Kbytes of the data space memory map can optionally be mapped into program space at any 16K program word boundary defined by the 8-bit Program Space Visibility Page (PSVPAG) register. The program to data space mapping feature lets any instruction access program space as if it were data space. The data space also includes 2 Kbytes of DMA RAM, which is primarily used for DMA data transfers, but may be used as general purpose RAM. 3.2 Special MCU Features The PIC24HJXXXGPX06A/X08A/X10A features a 17-bit by 17-bit, single-cycle multiplier. The multiplier can perform signed, unsigned and mixed-sign multiplication. Using a 17-bit by 17-bit multiplier for 16-bit by 16-bit multiplication makes mixed-sign multiplication possible. The PIC24HJXXXGPX06A/X08A/X10A supports 16/16 and 32/16 integer divide operations. All divide instructions are iterative operations. They must be executed within a REPEAT loop, resulting in a total execution time of 19 instruction cycles. The divide operation can be interrupted during any of those 19 cycles without loss of data. A multi-bit data shifter is used to perform up to a 16-bit, left or right shift in a single cycle. The PIC24HJXXXGPX06A/X08A/X10A devices have sixteen, 16-bit working registers in the programmer's model. Each of the working registers can serve as a data, address or address offset register. The 16th working register (W15) operates as a software Stack Pointer (SP) for interrupts and calls. The PIC24HJXXXGPX06A/X08A/X10A instruction set includes many addressing modes and is designed for optimum C compiler efficiency. For most instructions, the PIC24HJXXXGPX06A/X08A/X10A is capable of executing a data (or program data) memory read, a working register (data) read, a data memory write and a program (instruction) memory read per instruction cycle. As a result, three parameter instructions can be supported, allowing A + B = C operations to be executed in a single cycle. A block diagram of the CPU is shown in Figure 3-1, and the programmer's model for the PIC24HJXXXGPX06A/X08A/X10A is shown in Figure 3-2. 2009-2012 Microchip Technology Inc.

DS70592D-page 27 PIC24HJXXXGPX06A/X08A/X10A 3.4 Arithmetic Logic Unit (ALU) The PIC24HJXXXGPX06A/X08A/X10A ALU is 16 bits wide and is capable of addition, subtraction, bit shifts and logic operations. Unless otherwise mentioned, arithmetic operations are 2's complement in nature. Depending on the operation, the ALU may affect the values of the Carry (C), Zero (Z), Negative (N), Overflow (OV) and Digit Carry (DC) Status bits in the SR register. The C and DC Status bits operate as Borrow and Digit Borrow bits, respectively, for subtraction operations. The ALU can perform 8-bit or 16-bit operations, depending on the mode of the instruction that is used. Data for the ALU operation can come from the W register array, or data memory, depending on the addressing mode of the instruction. Likewise, output data from the ALU can be written to the W register array or a data memory location. Refer to the "16-bit MCU and DSC Programmer's Reference Manual" (DS70157) for information on the SR bits affected by each instruction. The PIC24HJXXXGPX06A/X08A/X10A CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 3.4.1 MULTIPLIER 3.4.2 DIVIDER The divide block supports 32-bit/16-bit and 16-bit/16-bit signed and unsigned integer divide operations with the following data sizes: * * * * 32-bit signed/16-bit signed divide 32-bit unsigned/16-bit unsigned divide 16-bit signed/16-bit signed divide 16-bit unsigned/16-bit unsigned divide The quotient for all divide instructions ends up in W0 and the remainder in W1. Sixteen-bit signed and unsigned DIV instructions can specify any W register for both the 16-bit divisor (Wn) and any W register (aligned) pair (W(m + 1):Wm) for the 32-bit dividend. The divide algorithm takes one cycle per bit of divisor, so both 32-bit/16-bit and 16-bit/16-bit instructions take the same number of cycles to execute. 3.4.3 MULTI-BIT DATA SHIFTER The multi-bit data shifter is capable of performing up to 16-bit arithmetic or logic right shifts, or up to 16-bit left shifts in a single cycle. The source can be either a working register or a memory location. The shifter requires a signed binary value to determine both the magnitude (number of bits) and direction of the shift operation. A positive value shifts the operand right. A negative value shifts the operand left. A value of `0' does not modify the operand. Using the high-speed 17-bit x 17-bit multiplier, the ALU supports unsigned, signed or mixed-sign operation in several multiplication modes: * * * * * * * 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit unsigned x 16-bit unsigned 16-bit unsigned x 5-bit (literal) unsigned 16-bit unsigned x 16-bit signed 8-bit unsigned x 8-bit unsigned DS70592D-page 28 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 4.0 MEMORY ORGANIZATION 4.1 This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 3. "Data Memory" (DS70202) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). Note: The PIC24HJXXXGPX06A/X08A/X10A architecture features separate program and data memory spaces and buses. This architecture also allows the direct access of program memory from the data space during code execution. FIGURE 4-1: The program address memory space of the PIC24HJXXXGPX06A/X08A/X10A devices is 4M instructions. The space is addressable by a 24-bit value derived from either the 23-bit Program Counter (PC) during program execution, or from table operation or data space remapping as described in Section 4.4 "Interfacing Program and Data Memory Spaces". User access to the program memory space is restricted to the lower half of the address range (0x000000 to 0x7FFFFF). The exception is the use of TBLRD/TBLWT operations, which use TBLPAG<7> to permit access to the Configuration bits and Device ID sections of the configuration memory space. Memory maps for the PIC24HJXXXGPX06A/X08A/ X10A family of devices are shown in Figure 4-1.

A hardware Reset vector is provided to redirect code execution from the default value of the PC on device Reset to the actual start of code. A GOTO instruction is programmed by the user at 0x000000, with the actual address for the start of code at 0x000002. The program memory space is organized in wordaddressable blocks. Although it is treated as 24 bits wide, it is more appropriate to think of each address of the program memory as a lower and upper word, with the upper byte of the upper word being unimplemented. The lower word always has an even address, while the upper word has an odd address (Figure 4-2). PIC24HJXXXGPX06A/X08A/X10A devices also have two interrupt vector tables, located from 0x000004 to 0x0000FF and 0x000100 to 0x0001FF. These vector tables allow each of the many device interrupt sources to be handled by separate Interrupt Service Routines (ISRs). A more detailed discussion of the interrupt vector tables is provided in Section 7.1 "Interrupt Vector Table". Program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented by two during code execution. This arrangement also provides compatibility with data memory space addressing and makes it possible to access data in the program memory space.

PIC24HJXXXGPX06A/X08A/X10A 4.2 Data Address Space The PIC24HJXXXGPX06A/X08A/X10A CPU has a separate 16-bit wide data memory space. The data space is accessed using separate Address Generation Units (AGUs) for read and write operations. Data memory maps of devices with different RAM sizes are shown in Figure 4-3 and Figure 4-4. All Effective Addresses (EAs) in the data memory space are 16 bits wide and point to bytes within the data space. This arrangement gives a data space address range of 64 Kbytes or 32K words. The lower half of the data memory space (that is, when EA<15> = 0) is used for implemented memory addresses, while the upper half (EA<15> = 1) is reserved for the Program Space Visibility area (see Section 4.4.3 "Reading Data from Program Memory Using Program Space Visibility"). PIC24HJXXXGPX06A/X08A/X10A devices implement up to 16 Kbytes of data memory. Should an EA point to a location outside of this area, an all-zero word or byte will be returned. 4.2.1 DATA SPACE WIDTH The data memory space is organized in byte addressable, 16-bit wide blocks. Data is aligned in data memory and registers as 16-bit words, but all data space EAs resolve to bytes. The Least Significant Bytes of each word have even addresses, while the Most Significant Bytes have odd addresses. 4.2.2 DATA MEMORY ORGANIZATION AND ALIGNMENT To maintain backward compatibility with PIC(R) MCU devices and improve data space memory usage efficiency, the PIC24HJXXXGPX06A/X08A/X10A instruction set supports both word and byte operations. As a consequence of byte accessibility, all effective address calculations are internally scaled to step through word-aligned memory. For example, the core recognizes that Post-Modified Register Indirect Addressing mode [Ws++] will result in a value of Ws + 1 for byte operations and Ws + 2 for word operations. Data byte reads will read the complete word that contains the byte, using the Least Significant bit (LSb) of any EA to determine which byte to select. The selected byte is placed onto the Least Significant Byte (LSB) of the data path. That is, data memory and registers are organized as two parallel byte-wide entities with shared (word) address decode but separate write lines. Data byte writes only write to the corresponding side of the array or register which matches the byte address. 2009-2012 Microchip Technology Inc. All word accesses must be aligned to an even address. Misaligned word data fetches are not supported, so care must be taken when mixing byte and word operations, or translating from 8-bit MCU code. If a misaligned read or write is attempted, an address error trap is generated. If the error occurred on a read, the instruction underway is completed; if it occurred on a write, the instruction will be executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the Least Significant Byte. The Most Significant Byte (MSB) is not modified. A sign-extend instruction (SE) is provided to allow users to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, users can clear the Most Significant Byte of any W register by executing a zero-extend (ZE) instruction on the appropriate address. 4.2.3 SFR SPACE The first 2 Kbytes of the Near Data Space, from 0x0000 to 0x07FF, is primarily occupied by Special Function Registers (SFRs). These are used by the PIC24HJXXXGPX06A/X08A/X10A core and peripheral modules for controlling the operation of the device. SFRs are distributed among the modules that they control, and are generally grouped together by module. Much of the SFR space contains unused addresses; these are read as `0'. A complete listing of implemented SFRs, including their addresses, is shown in Table 4-1 through Table 4-33. Note: 4.2.4 The actual set of peripheral features and interrupts varies by the device. Please refer to the corresponding device tables and pinout diagrams for device-specific information. NEAR DATA SPACE The 8-Kbyte area between 0x0000 and 0x1FFF is referred to as the Near Data Space. Locations in this space are directly addressable via a 13-bit absolute address field within all memory direct instructions. Additionally, the whole data space is addressable using MOV instructions, which support Memory Direct Addressing mode with a 16-bit address field, or by using Indirect Addressing mode using a working register as an Address Pointer.

Memory locations in the DMA RAM space are accessible simultaneously by the CPU and the DMA controller module. DMA RAM is utilized by the DMA controller to store data to be transferred to various peripherals using DMA, as well as data 0xFFFE transferred from various peripherals using DMA. The DMA RAM can be accessed by the DMA controller without having to steal cycles from the CPU. When the CPU and the DMA controller attempt to concurrently write to the same DMA RAM location, the hardware ensures that the CPU is given precedence in accessing the DMA RAM location. Therefore, the DMA RAM provides a reliable means of transferring DMA data without ever having to stall the CPU. Note: 2009-2012 Microchip Technology Inc. DMA RAM can be used for general purpose data storage if the DMA function is not required in an application. DS70592D-page 33 CPU CORE REGISTERS MAP All Resets 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A DS70592D-page 52 TABLE 4-31: PIC24HJXXXGPX06A/X08A/X10A 4.2.6 4.2.7 SOFTWARE STACK In addition to its use as a working register, the W15 register in the PIC24HJXXXGPX06A/X08A/X10A devices is also used as a software Stack Pointer. The Stack Pointer always points to the first available free word and grows from lower to higher addresses. It predecrements for stack pops and post-increments for stack pushes, as shown in Figure 4-5. For a PC push during any CALL instruction, the MSB of the PC is zeroextended before the push, ensuring that the MSB is always clear. Note: A PC push during exception processing concatenates the SRL register to the MSB of the PC prior to the push. The Stack Pointer Limit register (SPLIM) associated with the Stack Pointer sets an upper address boundary for the stack. SPLIM is uninitialized at Reset. As is the case for the Stack Pointer, SPLIM<0> is forced to `0' because all stack operations must be word-aligned. Whenever an EA is generated using W15 as a source or destination pointer, the resulting address is compared with the value in SPLIM. If the contents of the Stack Pointer (W15) and the SPLIM register are equal and a push operation is performed, a stack error trap will not occur. The stack error trap will occur on a subsequent push operation. Thus, for example, if it is desirable to cause a stack error trap when the stack grows beyond address 0x2000 in RAM, initialize the SPLIM with the value 0x1FFE. Similarly, a Stack Pointer underflow (stack error) trap is generated when the Stack Pointer address is found to be less than 0x0800. This prevents the stack from interfering with the Special Function Register (SFR) space. A write to the SPLIM register should not be immediately followed by an indirect read operation using W15.

BSRAM (Secure RAM segment for BS) is accessible only from the Boot Segment Flash code, when enabled. SSRAM (Secure RAM segment for RAM) is accessible only from the Secure Segment Flash code, when enabled. See Table 4-1 for an overview of the BSRAM and SSRAM SFRs. 4.3 Instruction Addressing Modes The addressing modes in Table 4-34 form the basis of the addressing modes optimized to support the specific features of individual instructions. The addressing modes provided in the MAC class of instructions are somewhat different from those in the other instruction types. 4.3.1 FILE REGISTER INSTRUCTIONS Most file register instructions use a 13-bit address field (f) to directly address data present in the first 8192 bytes of data memory (Near Data Space). Most file register instructions employ a working register, W0, which is denoted as WREG in these instructions. The destination is typically either the same file register or WREG (with the exception of the MUL instruction), which writes the result to a register or register pair. The MOV instruction allows additional flexibility and can access the entire data space. 4.3.2 MCU INSTRUCTIONS The 3-operand MCU instructions are of the form: Operand 3 = Operand 1 <function> Operand 2 where: Operand 1 is always a working register (i.e., the addressing mode can only be Register Direct) which is referred to as Wb. Operand 2 can be a W register, fetched from data memory, or a 5-bit literal. The result location can be either a W register or a data memory location. The following addressing modes are supported by MCU instructions: W15 (before CALL) W15 (after CALL) POP : [--W15] PUSH : [W15++] * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified 5-bit or 10-bit Literal Note: 2009-2012 Microchip Technology Inc. DATA RAM PROTECTION FEATURE Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes. DS70592D-page 53 PIC24HJXXXGPX06A/X08A/X10A TABLE 4-34: FUNDAMENTAL ADDRESSING MODES SUPPORTED Addressing Mode Description File Register Direct The address of the file register is specified explicitly. Register Direct The contents of a register are accessed directly. Register Indirect The contents of Wn forms the EA. Register Indirect Post-Modified The contents of Wn forms the EA. Wn is post-modified (incremented or decremented) by a constant value. Register Indirect Pre-Modified Wn is pre-modified (incremented or decremented) by a signed constant value to form the EA. Register Indirect with Register Offset The sum of Wn and Wb forms the EA. Register Indirect with Literal Offset 4.3.3 The sum of Wn and a literal forms the EA. MOVE INSTRUCTIONS Move instructions provide a greater degree of addressing flexibility than other instructions. In addition to the Addressing modes supported by most MCU instructions, move instructions also support Register Indirect with Register Offset Addressing mode, also referred to as Register Indexed mode. Note: For the MOV instructions, the Addressing mode specified in the instruction can differ for the source and destination EA. However, the 4-bit Wb (Register Offset) field is shared between both source and destination (but typically only used by one). In summary, the following Addressing modes are supported by move instructions: * * * * * * * * Register Direct Register Indirect Register Indirect Post-modified Register Indirect Pre-modified Register Indirect with Register Offset (Indexed) Register Indirect with Literal Offset 8-bit Literal 16-bit Literal Note: 4.3.4 Not all instructions support all the Addressing modes given above. Individual instructions may support different subsets of these Addressing modes. OTHER INSTRUCTIONS Besides the various addressing modes outlined above, some instructions use literal constants of various sizes. For example, BRA (branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI instruction uses a 14-bit unsigned literal field. In some instructions, the source of an operand or result is implied by the opcode itself. Certain operations, such as NOP, do not have any operands. DS70592D-page 54 4.4 Interfacing Program and Data Memory Spaces The PIC24HJXXXGPX06A/X08A/X10A architecture uses a 24-bit wide program space and a 16-bit wide data space. The architecture is also a modified Harvard scheme, meaning that data can also be present in the program space. To use this data successfully, it must be accessed in a way that preserves the alignment of information in both spaces. Aside from normal execution, the PIC24HJXXXGPX06A/X08A/X10A architecture provides two methods by which program space can be accessed during operation: * Using table instructions to access individual bytes or words anywhere in the program space * Remapping a portion of the program space into the data space (Program Space Visibility) Table instructions allow an application to read or write to small areas of the program memory. This capability makes the method ideal for accessing data tables that need to be updated from time to time. It also allows access to all bytes of the program word. The remapping method allows an application to access a large block of data on a read-only basis, which is ideal for look ups from a large table of static data. It can only access the least significant word of the program word. 4.4.1 ADDRESSING PROGRAM SPACE Since the address ranges for the data and program spaces are 16 and 24 bits, respectively, a method is needed to create a 23-bit or 24-bit program address from 16-bit data registers. The solution depends on the interface method to be used. For table operations, the 8-bit Table Page register (TBLPAG) is used to define a 32K word region within the program space. This is concatenated with a 16-bit EA to arrive at a full 24-bit program space address. In this format, the Most Significant bit of TBLPAG is used to determine if the operation occurs in the user memory (TBLPAG<7> = 0) or the configuration memory (TBLPAG<7> = 1). 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A For remapping operations, the 8-bit Program Space Visibility register (PSVPAG) is used to define a 16K word page in the program space. When the Most Significant bit of the EA is `1', PSVPAG is concatenated with the lower 15 bits of the EA to form a 23-bit program space address. Unlike table operations, this limits remapping operations strictly to the user memory area. TABLE 4-35: Table 4-35 and Figure 4-6 show how the program EA is created for table operations and remapping accesses from the data EA. Here, P<23:0> refers to a program space word, whereas D<15:0> refers to a data space word.

PIC24HJXXXGPX06A/X08A/X10A 4.4.2 DATA ACCESS FROM PROGRAM MEMORY USING TABLE INSTRUCTIONS 2. The TBLRDL and TBLWTL instructions offer a direct method of reading or writing the lower word of any address within the program space without going through data space. The TBLRDH and TBLWTH instructions are the only method to read or write the upper 8 bits of a program space word as data. The PC is incremented by two for each successive 24-bit program word. This allows program memory addresses to directly map to data space addresses. Program memory can thus be regarded as two 16-bit, word wide address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space which contains the least significant data word and TBLRDH and TBLWTH access the space which contains the upper data byte. Two table instructions are provided to move byte or word sized (16-bit) data to and from program space. Both function as either byte or word operations. 1. TBLRDL (Table Read Low): In Word mode, it maps the lower word of the program space location (P<15:0>) to a data address (D<15:0>). TBLRDH (Table Read High): In Word mode, it maps the entire upper word of a program address (P<23:16>) to a data address. Note that D<15:8>, the `phantom byte', will always be `0'. In Byte mode, it maps the upper or lower byte of the program word to D<7:0> of the data address, as above. Note that the data will always be `0' when the upper `phantom' byte is selected (Byte Select = 1). In a similar fashion, two table instructions, TBLWTH and TBLWTL, are used to write individual bytes or words to a program space address. The details of their operation are explained in Section 5.0 "Flash Program Memory". For all table operations, the area of program memory space to be accessed is determined by the Table Page register (TBLPAG). TBLPAG covers the entire program memory space of the device, including user and configuration spaces. When TBLPAG<7> = 0, the table page is located in the user memory space. When TBLPAG<7> = 1, the page is located in configuration space. In Byte mode, either the upper or lower byte of the lower program word is mapped to the lower byte of a data address. The upper byte is selected when Byte Select is `1'; the lower byte is selected when it is `0'. FIGURE 4-7: ACCESSING PROGRAM MEMORY WITH TABLE INSTRUCTIONS Program Space TBLPAG 02 23 15 0 0x000000 23 16 8 0 00000000 0x020000 0x030000 00000000 00000000 00000000 `Phantom' Byte TBLRDH.B (Wn<0> = 0) TBLRDL.B (Wn<0> = 1) TBLRDL.B (Wn<0> = 0) TBLRDL.W 0x800000 2009-2012 Microchip Technology Inc. The address for the table operation is determined by the data EA within the page defined by the TBLPAG register. Only read operations are shown; write operations are also valid in the user memory area. DS70592D-page 57 PIC24HJXXXGPX06A/X08A/X10A 4.4.3 READING DATA FROM PROGRAM MEMORY USING PROGRAM SPACE VISIBILITY The upper 32 Kbytes of data space may optionally be mapped into any 16K word page of the program space. This option provides transparent access of stored constant data from the data space without the need to use special instructions (i.e., TBLRDL/H). Program space access through the data space occurs if the Most Significant bit of the data space EA is `1' and program space visibility is enabled by setting the PSV bit in the Core Control register (CORCON<2>). The location of the program memory space to be mapped into the data space is determined by the Program Space Visibility Page register (PSVPAG). This 8-bit register defines any one of 256 possible pages of 16K words in program space. In effect, PSVPAG functions as the upper 8 bits of the program memory address, with the 15 bits of the EA functioning as the lower bits. Note that by incrementing the PC by 2 for each program memory word, the lower 15 bits of data space addresses directly map to the lower 15 bits in the corresponding program space addresses. Data reads to this area add an additional cycle to the instruction being executed, since two program memory fetches are required. Although each data space address, 0x8000 and higher, maps directly into a corresponding program memory address (see Figure 4-8), only the lower 16 bits of the FIGURE 4-8: 24-bit program word are used to contain the data. The upper 8 bits of any program space location used as data should be programmed with `1111 1111' or `0000 0000' to force a NOP. This prevents possible issues should the area of code ever be accidentally executed. Note: PSV access is temporarily disabled during table reads/writes. For operations that use PSV and are executed outside a REPEAT loop, the MOV and MOV.D instructions require one instruction cycle in addition to the specified execution time. All other instructions require two instruction cycles in addition to the specified execution time. For operations that use PSV, which are executed inside a REPEAT loop, there will be some instances that require two instruction cycles in addition to the specified execution time of the instruction: * Execution in the first iteration * Execution in the last iteration * Execution prior to exiting the loop due to an interrupt * Execution upon re-entering the loop after an interrupt is serviced Any other iteration of the REPEAT loop will allow the instruction accessing data, using PSV, to execute in a single cycle.

This corresponds exactly to the same lower 15 bits of the actual program space address. 2009-2012 Microchip Technology Inc.

FLASH PROGRAM MEMORY Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 5. "Flash Programming" (DS70191) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). RTSP is accomplished using TBLRD (table read) and TBLWT (table write) instructions. With RTSP, the user can write program memory data either in blocks or `rows' of 64 instructions (192 bytes) at a time, or single instructions and erase program memory in blocks or `pages' of 512 instructions (1536 bytes) at a time. 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 5.1 The PIC24HJXXXGPX06A/X08A/X10A devices contain internal Flash program memory for storing and executing application code. The memory is readable, writable and erasable during normal operation over the entire VDD range. Flash memory can be programmed in two ways: 1. 2. In-Circuit Serial ProgrammingTM (ICSPTM) programming capability Run-Time Self-Programming (RTSP) ICSP programming capability allows a PIC24HJXXXGPX06A/X08A/X10A device to be serially programmed while in the end application circuit. This is simply done with two lines for programming clock and programming data (one of the alternate programming pin pairs: PGECx/PGEDx, and three other FIGURE 5-1: Table Instructions and Flash Programming Regardless of the method used, all programming of Flash memory is done with the table read and table write instructions. These allow direct read and write access to the program memory space from the data memory while the device is in normal operating mode. The 24-bit target address in the program memory is formed using bits<7:0> of the TBLPAG register and the Effective Address (EA) from a W register specified in the table instruction, as shown in Figure 5-1. The TBLRDL and the TBLWTL instructions are used to read or write to bits<15:0> of program memory. TBLRDL and TBLWTL can access program memory in both Word and Byte modes. The TBLRDH and TBLWTH instructions are used to read or write to bits<23:16> of program memory. TBLRDH and TBLWTH can also access program memory in Word or Byte mode.

RTSP allows the user to erase a page of memory, which consists of eight rows (512 instructions) at a time, and to program one row or one word at a time. Table 24-12 displays typical erase and programming times. The 8-row erase pages and single row write rows are edge-aligned, from the beginning of program memory, on boundaries of 1536 bytes and 192 bytes, respectively. The program memory implements holding buffers that can contain 64 instructions of programming data. Prior to the actual programming operation, the write data must be loaded into the buffers in sequential order. The instruction words loaded must always be from a group of 64 boundary. The basic sequence for RTSP programming is to set up a Table Pointer, then do a series of TBLWT instructions to load the buffers. Programming is performed by setting the control bits in the NVMCON register. A total of 64 TBLWTL and TBLWTH instructions are required to load the instructions. All of the table write operations are single-word writes (two instruction cycles) because only the buffers are written. A programming cycle is required for programming each row. 5.3 Programming Operations A complete programming sequence is necessary for programming or erasing the internal Flash in RTSP mode. The processor stalls (waits) until the programming operation is finished. The programming time depends on the FRC accuracy (see Table 24-19) and the value of the FRC Oscillator Tuning register (see Register 9-4). Use the following formula to calculate the minimum and maximum values for the Row Write Time, Page Erase Time and Word Write Cycle Time parameters (see Table 24-12). EQUATION 5-1: For example, if the device is operating at +125C, the FRC accuracy will be 5%. If the TUN<5:0> bits (see Register 9-4) are set to `b111111, the minimum row write time is equal to Equation 5-2.

NVMKEY is a write-only register that is used for write protection. To start a programming or erase sequence, the user must consecutively write 0x55 and 0xAA to the NVMKEY register.

The user can program one row of program Flash memory at a time. To do this, it is necessary to erase the 8-row erase page that contains the desired row. The general process is: 1. 2. 3. Read eight rows of program memory (512 instructions) and store in data RAM. Update the program data in RAM with the desired new data. Erase the page (see Example 5-1): a) Set the NVMOP bits (NVMCON<3:0>) to `0010' to configure for block erase. Set the ERASE (NVMCON<6>) and WREN (NVMCON<14>) bits. b) Write the starting address of the page to be erased into the TBLPAG and W registers. c) Perform a dummy table write operation (TBLWTL) to any address within the page that needs to be erased. d) Write 0x55 to NVMKEY. e) Write 0xAA to NVMKEY. f) Set the WR bit (NVMCON<15>). The erase cycle begins and the CPU stalls for the duration of the erase cycle. When the erase is done, the WR bit is cleared automatically. EXAMPLE 5-1: Note: For protection against accidental operations, the write initiate sequence for NVMKEY must be used to allow any erase or program operation to proceed. After the programming command has been executed, the user must wait for the programming time until programming is complete. The two instructions following the start of the programming sequence should be NOPs, as shown in Example 5-3. ERASING A PROGRAM MEMORY PAGE ; Set up NVMCON for block erase operation MOV #0x4042, W0 MOV W0, NVMCON ; Init pointer to row to be ERASED MOV #tblpage(PROG_ADDR), W0 MOV W0, TBLPAG MOV #tbloffset(PROG_ADDR), W0 TBLWTL W0, [W0] DISI #5 MOV MOV MOV MOV BSET NOP NOP 6. Write the first 64 instructions from data RAM into the program memory buffers (see Example 5-2). Write the program block to Flash memory: a) Set the NVMOP bits to `0001' to configure for row programming. Clear the ERASE bit and set the WREN bit. b) Write 0x55 to NVMKEY. c) Write 0xAA to NVMKEY. d) Set the WR bit. The programming cycle begins and the CPU stalls for the duration of the write cycle. When the write to Flash memory is done, the WR bit is cleared automatically. Repeat steps 4 and 5, using the next available 64 instructions from the block in data RAM by incrementing the value in TBLPAG, until all 512 instructions are written back to Flash memory. #0x55, W0 W0, NVMKEY #0xAA, W1 W1, NVMKEY NVMCON, #WR ; ; Initialize NVMCON ; ; ; ; ; ; ; ; ; ; ; ; Initialize PM Page Boundary SFR Initialize in-page EA<15:0> pointer Set base address of erase block Block all interrupts with priority <7 for next 5 instructions Write the 55 key Write the AA key Start the erase sequence Insert two NOPs after the erase command is asserted A program memory page erase operation is set up by performing a dummy table write (TBLWTL) operation to any address within the page.

Many registers associated with the CPU and peripherals are forced to a known Reset state. Most registers are unaffected by a Reset; their status is unknown on POR and unchanged by all other Resets. Note: Refer to the specific peripheral or CPU section of this data sheet for register Reset states. All types of device Reset will set a corresponding status bit in the RCON register to indicate the type of Reset (see Register 6-1). A POR will clear all bits, except for the POR bit (RCON<0>), that are set. The user can set or clear any bit at any time during code execution. The RCON bits only serve as status bits. Setting a particular Reset status bit in software does not cause a device Reset to occur. The RCON register also has other bits associated with the Watchdog Timer and device power-saving states. The function of these bits is discussed in other sections of this manual. Note: The status bits in the RCON register should be cleared after they are read so that the next RCON register value after a device Reset will be meaningful.

Clock Source Selection at Reset If clock switching is enabled, the system clock source at device Reset is chosen, as shown in Table 6-2. If clock switching is disabled, the system clock source is always selected according to the oscillator Configuration bits. Refer to Section 9.0 "Oscillator Configuration" for further details. TABLE 6-2: Reset Type POR BOR MCLR WDTR OSCILLATOR SELECTION vs. TYPE OF RESET (CLOCK SWITCHING ENABLED) Clock Source Determinant 6.2 Device Reset Times The Reset times for various types of device Reset are summarized in Table 6-3. The system Reset signal is released after the POR and PWRT delay times expire. The time at which the device actually begins to execute code also depends on the system oscillator delays, which include the Oscillator Start-up Timer (OST) and the PLL lock time. The OST and PLL lock times occur in parallel with the applicable reset delay times. The FSCM delay determines the time at which the FSCM begins to monitor the system clock source after the reset signal is released.

TSTARTUP = Conditional POR delay of 20 s nominal (if on-chip regulator is enabled) or 64 ms nominal Power-up Timer delay (if regulator is disabled). TSTARTUP is also applied to all returns from powered-down states, including waking from Sleep mode, only if the regulator is enabled. TRST = Internal state Reset time (20 s nominal). TOST = Oscillator Start-up Timer. A 10-bit counter counts 1024 oscillator periods before releasing the oscillator clock to the system. TLOCK = PLL lock time (20 s nominal). TFSCM = Fail-Safe Clock Monitor delay (100 s nominal). POR AND LONG OSCILLATOR START-UP TIMES The oscillator start-up circuitry and its associated delay timers are not linked to the device Reset delays that occur at power-up. Some crystal circuits (especially low-frequency crystals) have a relatively long start-up time. Therefore, one or more of the following conditions is possible after the Reset signal is released: * The oscillator circuit has not begun to oscillate * The Oscillator Start-up Timer has not expired (if a crystal oscillator is used) * The PLL has not achieved a lock (if PLL is used) The device will not begin to execute code until a valid clock source has been released to the system. Therefore, the oscillator and PLL start-up delays must be considered when the Reset delay time must be known. 6.2.2 FAIL-SAFE CLOCK MONITOR (FSCM) AND DEVICE RESETS If the FSCM is enabled, it begins to monitor the system clock source when the Reset signal is released. If a valid clock source is not available at this time, the device automatically switches to the FRC oscillator and the user can switch to the desired crystal oscillator in the Trap Service Routine. DS70592D-page 68 6.2.2.1 FSCM Delay for Crystal and PLL Clock Sources When the system clock source is provided by a crystal oscillator and/or the PLL, a small delay, TFSCM, is automatically inserted after the POR and PWRT delay times. The FSCM does not begin to monitor the system clock source until this delay expires. The FSCM delay time is nominally 500 s and provides additional time for the oscillator and/or PLL to stabilize. In most cases, the FSCM delay prevents an oscillator failure trap at a device Reset when the PWRT is disabled. 6.3 Special Function Register Reset States Most of the Special Function Registers (SFRs) associated with the CPU and peripherals are reset to a particular value at a device Reset. The SFRs are grouped by their peripheral or CPU function and their Reset values are specified in each section of this manual. The Reset value for each SFR does not depend on the type of Reset, with the exception of two registers. The Reset value for the Reset Control register, RCON, depends on the type of device Reset. The Reset value for the Oscillator Control register, OSCCON, depends on the type of Reset and the programmed values of the oscillator Configuration bits in the FOSC Configuration register. 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 7.0 INTERRUPT CONTROLLER Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 6. "Interrupts" (DS70184) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The PIC24HJXXXGPX06A/X08A/X10A interrupt controller reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the PIC24HJXXXGPX06A/X08A/X10A CPU. It has the following features: * * * * Up to 8 processor exceptions and software traps 7 user-selectable priority levels Interrupt Vector Table (IVT) with up to 118 vectors A unique vector for each interrupt or exception source * Fixed priority within a specified user priority level * Alternate Interrupt Vector Table (AIVT) for debug support * Fixed interrupt entry and return latencies 7.1 7.1.1 ALTERNATE VECTOR TABLE The Alternate Interrupt Vector Table (AIVT) is located after the IVT, as shown in Figure 7-1. Access to the AIVT is provided by the ALTIVT control bit (INTCON2<15>). If the ALTIVT bit is set, all interrupt and exception processes use the alternate vectors instead of the default vectors. The alternate vectors are organized in the same manner as the default vectors. The AIVT supports debugging by providing a means to switch between an application and a support environment without requiring the interrupt vectors to be reprogrammed. This feature also enables switching between applications for evaluation of different software algorithms at run time. If the AIVT is not needed, the AIVT should be programmed with the same addresses used in the IVT. 7.2 Reset Sequence A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The PIC24HJXXXGPX06A/X08A/X10A device clears its registers in response to a Reset which forces the PC to zero. The digital signal controller then begins program execution at location 0x000000. The user programs a GOTO instruction at the Reset address which redirects program execution to the appropriate start-up routine. Note: Any unimplemented or unused vector locations in the IVT and AIVT should be programmed with the address of a default interrupt handler routine that contains a RESET instruction. Interrupt Vector Table The Interrupt Vector Table (IVT) is shown in Figure 7-1. The IVT resides in program memory, starting at location 000004h. The IVT contains 126 vectors consisting of 8 nonmaskable trap vectors plus up to 118 sources of interrupt. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). Interrupt vectors are prioritized in terms of their natural priority; this priority is linked to their position in the vector table. All other things being equal, lower addresses have a higher natural priority. For example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address. PIC24HJXXXGPX06A/X08A/X10A devices implement up to 61 unique interrupts and 5 nonmaskable traps. These are summarized in Table 7-1 and Table 7-2. 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 7.3 Interrupt Control and Status Registers PIC24HJXXXGPX06A/X08A/X10A devices implement a total of 30 registers for the interrupt controller: * * * * * * INTCON1 INTCON2 IFS0 through IFS4 IEC0 through IEC4 IPC0 through IPC17 INTTREG Global interrupt control functions are controlled from INTCON1 and INTCON2. INTCON1 contains the Interrupt Nesting Disable (NSTDIS) bit as well as the control and status flags for the processor trap sources. The INTCON2 register controls the external interrupt request signal behavior and the use of the Alternate Interrupt Vector Table. The IFS registers maintain all of the interrupt request flags. Each source of interrupt has a Status bit, which is set by the respective peripherals or external signal and is cleared via software. The IEC registers maintain all of the interrupt enable bits. These control bits are used to individually enable interrupts from the peripherals or external signals. The IPC registers are used to set the interrupt priority level for each source of interrupt. Each user interrupt source can be assigned to one of eight priority levels. The INTTREG register contains the associated interrupt vector number and the new CPU interrupt priority level, which are latched into vector number (VECNUM<6:0>) and Interrupt level (ILR<3:0>) bit fields in the INTTREG register. The new interrupt priority level is the priority of the pending interrupt. The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence that they are listed in Table 7-1. For example, the INT0 (External Interrupt 0) is shown as having vector number 8 and a natural order priority of 0. Thus, the INT0IF bit is found in IFS0<0>, the INT0IE bit in IEC0<0>, and the INT0IP bits in the first position of IPC0 (IPC0<2:0>). Although they are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. The CPU STATUS register, SR, contains the IPL<2:0> bits (SR<7:5>). These bits indicate the current CPU interrupt priority level. The user can change the current CPU priority level by writing to the IPL bits. The CORCON register contains the IPL3 bit which, together with IPL<2:0>, also indicates the current CPU priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software. All Interrupt registers are described in Register 7-1 through Register 7-32. 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 7.4 Interrupt Setup Procedures 7.4.1 INITIALIZATION To configure an interrupt source: 1. 2. Set the NSTDIS bit (INTCON1<15>) if nested interrupts are not desired. Select the user-assigned priority level for the interrupt source by writing the control bits in the appropriate IPCx register. The priority level will depend on the specific application and type of interrupt source. If multiple priority levels are not desired, the IPCx register control bits for all enabled interrupt sources may be programmed to the same non-zero value. Note: 3. 4. At a device Reset, the IPCx registers are initialized, such that all user interrupt sources are assigned to priority level 4. Clear the interrupt flag status bit associated with the peripheral in the associated IFSx register. Enable the interrupt source by setting the interrupt enable control bit associated with the source in the appropriate IECx register. 7.4.2 7.4.3 TRAP SERVICE ROUTINE A Trap Service Routine (TSR) is coded like an ISR, except that the appropriate trap status flag in the INTCON1 register must be cleared to avoid re-entry into the TSR. 7.4.4 INTERRUPT DISABLE All user interrupts can be disabled using the following procedure: 1. 2. Push the current SR value onto the software stack using the PUSH instruction. Force the CPU to priority level 7 by inclusive ORing the value 0x0E with SRL. To enable user interrupts, the POP instruction may be used to restore the previous SR value. Note that only user interrupts with a priority level of 7 or less can be disabled. Trap sources (level 8-level 15) cannot be disabled. The DISI instruction provides a convenient way to disable interrupts of priority levels 1-6 for a fixed period of time. Level 7 interrupt sources are not disabled by the DISI instruction. INTERRUPT SERVICE ROUTINE The method that is used to declare an ISR and initialize the IVT with the correct vector address will depend on the programming language (i.e., C or assembler) and the language development toolsuite that is used to develop the application. In general, the user must clear the interrupt flag in the appropriate IFSx register for the source of interrupt that the ISR handles. Otherwise, the ISR will be re-entered immediately after exiting the routine. If the ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved PC value, SRL value and old CPU priority level. 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 8.0 DIRECT MEMORY ACCESS (DMA) Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 22. "Direct Memory Access (DMA)" (DS70182) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. Direct Memory Access (DMA) is a very efficient mechanism of copying data between peripheral SFRs (e.g., UART Receive register, Input Capture 1 buffer), and buffers or variables stored in RAM, with minimal CPU intervention. The DMA controller can automatically copy entire blocks of data without requiring the user software to read or write the peripheral Special Function Registers (SFRs) every time a peripheral interrupt occurs. The DMA controller uses a dedicated bus for data transfers and, therefore, does not steal cycles from the code execution flow of the CPU. To exploit the DMA capability, the corresponding user buffers or variables must be located in DMA RAM. The PIC24HJXXXGPX06A/X08A/X10A peripherals that can utilize DMA are listed in Table 8-1 along with their associated Interrupt Request (IRQ) numbers.

Each channel has its own set of control and status registers. Each DMA channel can be configured to copy data either from buffers stored in dual port DMA RAM to peripheral SFRs, or from peripheral SFRs to buffers in DMA RAM. The DMA controller supports the following features: * Word or byte sized data transfers * Transfers from peripheral to DMA RAM or DMA RAM to peripheral * Indirect Addressing of DMA RAM locations with or without automatic post-increment * Peripheral Indirect Addressing - In some peripherals, the DMA RAM read/write addresses may be partially derived from the peripheral * One-Shot Block Transfers - Terminating DMA transfer after one block transfer * Continuous Block Transfers - Reloading DMA RAM buffer start address after every block transfer is complete * Ping-Pong Mode - Switching between two DMA RAM start addresses between successive block transfers, thereby filling two buffers alternately * Automatic or manual initiation of block transfers * Each channel can select from 19 possible sources of data sources or destinations For each DMA channel, a DMA interrupt request is generated when a block transfer is complete. Alternatively, an interrupt can be generated when half of the block has been filled. 2009-2012 Microchip Technology Inc.

DS70592D-page 123 PIC24HJXXXGPX06A/X08A/X10A 9.1 CPU Clocking System There are seven system clock options provided by the PIC24HJXXXGPX06A/X08A/X10A: * * * * * * * FRC Oscillator FRC Oscillator with PLL Primary (XT, HS or EC) Oscillator Primary Oscillator with PLL Secondary (LP) Oscillator LPRC Oscillator FRC Oscillator with postscaler 9.1.1 SYSTEM CLOCK SOURCES The FRC (Fast RC) internal oscillator runs at a nominal frequency of 7.37 MHz. The user software can tune the FRC frequency. User software can optionally specify a factor (ranging from 1:2 to 1:256) by which the FRC clock frequency is divided. This factor is selected using the FRCDIV<2:0> (CLKDIV<10:8>) bits. (FOSC<1:0>), select the oscillator source that is used at a Power-on Reset. The FRC primary oscillator is the default (unprogrammed) selection. The Configuration bits allow users to choose between twelve different clock modes, shown in Table 9-1. The output of the oscillator (or the output of the PLL if a PLL mode has been selected) FOSC is divided by 2 to generate the device instruction clock (FCY) and the peripheral clock time base (FP). FCY defines the operating speed of the device, and speeds up to 40 MHz are supported by the PIC24HJXXXGPX06A/ X08A/X10A architecture. Instruction execution speed or device operating frequency, FCY, is calculated, as shown in Equation 9-1: EQUATION 9-1: F OSC F CY = ------------2 The primary oscillator can use one of the following as its clock source: * XT (Crystal): Crystals and ceramic resonators in the range of 3 MHz to 10 MHz. The crystal is connected to the OSC1 and OSC2 pins. * HS (High-Speed Crystal): Crystals in the range of 10 MHz to 40 MHz. The crystal is connected to the OSC1 and OSC2 pins. * EC (External Clock): External clock signal is directly applied to the OSC1 pin. The secondary (LP) oscillator is designed for low power and uses a 32.768 kHz crystal or ceramic resonator. The LP oscillator uses the SOSCI and SOSCO pins. The LPRC (Low-Power RC) internal oscIllator runs at a nominal frequency of 32.768 kHz. It is also used as a reference clock by the Watchdog Timer (WDT) and Fail-Safe Clock Monitor (FSCM). The clock signals generated by the FRC and primary oscillators can be optionally applied to an on-chip Phase-Locked Loop (PLL) to provide a wide range of output frequencies for device operation. PLL configuration is described in Section 9.1.3 "PLL Configuration". The FRC frequency depends on the FRC accuracy (see Table 24-19) and the value of the FRC Oscillator Tuning register (see Register 9-4). 9.1.2 SYSTEM CLOCK SELECTION The oscillator source that is used at a device Power-on Reset event is selected using Configuration bit settings. The oscillator Configuration bit settings are located in the Configuration registers in the program memory. (Refer to Section 21.1 "Configuration Bits" for further details.) The Initial Oscillator Selection Configuration bits, FNOSC<2:0> (FOSCSEL<2:0>), and the Primary Oscillator Mode Select Configuration bits, POSCMD<1:0> DS70592D-page 124 DEVICE OPERATING FREQUENCY 9.1.3 PLL CONFIGURATION The primary oscillator and internal FRC oscillator can optionally use an on-chip PLL to obtain higher speeds of operation. The PLL provides a significant amount of flexibility in selecting the device operating speed. A block diagram of the PLL is shown in Figure 9-2. The output of the primary oscillator or FRC, denoted as `FIN', is divided down by a prescale factor (N1) of 2, 3, ... or 33 before being provided to the PLL's Voltage Controlled Oscillator (VCO). The input to the VCO must be selected to be in the range of 0.8 MHz to 8 MHz. Since the minimum prescale factor is 2, this implies that FIN must be chosen to be in the range of 1.6 MHz to 16 MHz. The prescale factor `N1' is selected using the PLLPRE<4:0> bits (CLKDIV<4:0>). The PLL Feedback Divisor, selected using the PLLDIV<8:0> bits (PLLFBD<8:0>), provides a factor `M', by which the input to the VCO is multiplied. This factor must be selected such that the resulting VCO output frequency is in the range of 100 MHz to 200 MHz. The VCO output is further divided by a postscale factor `N2'. This factor is selected using the PLLPOST<1:0> bits (CLKDIV<7:6>). `N2' can be either 2, 4 or 8, and must be selected such that the PLL output frequency (FOSC) is in the range of 12.5 MHz to 80 MHz, which generates device operating speeds of 6.25-40 MIPS. For a primary oscillator or FRC oscillator, output `FIN', the PLL output `FOSC' is given by: EQUATION 9-2: FOSC CALCULATION M F OSC = F IN ------------------- N1 N2 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A For example, suppose a 10 MHz crystal is being used, with "XT with PLL" being the selected oscillator mode. If PLLPRE<4:0> = 0, then N1 = 2. This yields a VCO input of 10/2 = 5 MHz, which is within the acceptable range of 0.8-8 MHz. If PLLDIV<8:0> = 0x1E, then M = 32. This yields a VCO output of 5 x 32 = 160 MHz, which is within the 100-200 MHz ranged needed. EQUATION 9-3: XT WITH PLL MODE EXAMPLE 1 10000000 32 F OSC F CY = ------------- = --- ---------------------------------- = 40 MIPS 2 22 2 If PLLPOST<1:0> = 0, then N2 = 2. This provides a Fosc of 160/2 = 80 MHz. The resultant device operating speed is 80/2 = 40 MIPS.

PIC24HJXXXGPX06A/X08A/X10A 9.2 Clock Switching Operation Applications are free to switch between any of the four clock sources (Primary, LP, FRC and LPRC) under software control at any time. To limit the possible side effects that could result from this flexibility, PIC24HJXXXGPX06A/X08A/X10A devices have a safeguard lock built into the switch process. Note: 9.2.1 Primary Oscillator mode has three different submodes (XT, HS and EC) which are determined by the POSCMD<1:0> Configuration bits. While an application can switch to and from Primary Oscillator mode in software, it cannot switch between the different primary submodes without reprogramming the device. 2. If a valid clock switch has been initiated, the LOCK (OSCCON<5>) and the CF (OSCCON<3>) status bits are cleared. The new oscillator is turned on by the hardware if it is not currently running. If a crystal oscillator must be turned on, the hardware waits until the Oscillator Start-up Timer (OST) expires. If the new source is using the PLL, the hardware waits until a PLL lock is detected (LOCK = 1). The hardware waits for 10 clock cycles from the new clock source and then performs the clock switch. The hardware clears the OSWEN bit to indicate a successful clock transition. In addition, the NOSC bit values are transferred to the COSC status bits. The old clock source is turned off at this time, with the exception of LPRC (if WDT or FSCM are enabled) or LP (if LPOSCEN remains set). 3. 4. 5. 6. ENABLING CLOCK SWITCHING To enable clock switching, the FCKSM1 Configuration bit in the Configuration register must be programmed to `0'. (Refer to Section 21.1 "Configuration Bits" for further details.) If the FCKSM1 Configuration bit is unprogrammed (`1'), the clock switching function and Fail-Safe Clock Monitor function are disabled. This is the default setting. Note 1: The processor continues to execute code throughout the clock switching sequence. Timing sensitive code should not be executed during this time. 2: Direct clock switches between any primary oscillator mode with PLL and FRCPLL mode are not permitted. This applies to clock switches in either direction. In these instances, the application must switch to FRC mode as a transition clock source between the two PLL modes. 3: Refer to Section 7. "Oscillator" (DS70186) in the "dsPIC33F/PIC24H Family Reference Manual" for details. The NOSC control bits (OSCCON<10:8>) do not control the clock selection when clock switching is disabled. However, the COSC bits (OSCCON<14:12>) reflect the clock source selected by the FNOSC Configuration bits. The OSWEN control bit (OSCCON<0>) has no effect when clock switching is disabled. It is held at `0' at all times. 9.2.2 OSCILLATOR SWITCHING SEQUENCE At a minimum, performing a clock switch requires this basic sequence: 1. 2. 3. 4. 5. If desired, read the COSC bits (OSCCON<14:12>) to determine the current oscillator source. Perform the unlock sequence to allow a write to the OSCCON register high byte. Write the appropriate value to the NOSC control bits (OSCCON<10:8>) for the new oscillator source. Perform the unlock sequence to allow a write to the OSCCON register low byte. Set the OSWEN bit to initiate the oscillator switch. Once the basic sequence is completed, the system clock hardware responds automatically as follows: 1. The clock switching hardware compares the COSC status bits with the new value of the NOSC control bits. If they are the same, the clock switch is a redundant operation. In this case, the OSWEN bit is cleared automatically and the clock switch is aborted. 2009-2012 Microchip Technology Inc. 9.3 Fail-Safe Clock Monitor (FSCM) The Fail-Safe Clock Monitor (FSCM) allows the device to continue to operate even in the event of an oscillator failure. The FSCM function is enabled by programming. If the FSCM function is enabled, the LPRC internal oscillator runs at all times (except during Sleep mode) and is not subject to control by the Watchdog Timer. If an oscillator failure occurs, the FSCM generates a clock failure trap event and switches the system clock over to the FRC oscillator. Then the application program can either attempt to restart the oscillator or execute a controlled shutdown. The trap can be treated as a warm Reset by simply loading the Reset address into the oscillator fail trap vector. If the PLL multiplier is used to scale the system clock, the internal FRC is also multiplied by the same factor on clock failure. Essentially, the device switches to FRC with PLL on a clock failure.

PIC24HJXXXGPX06A/X08A/X10A 10.0 POWER-SAVING FEATURES Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 9. "Watchdog Timer and Power-Saving Modes" (DS70196) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The PIC24HJXXXGPX06A/X08A/X10A devices provide the ability to manage power consumption by selectively managing clocking to the CPU and the peripherals. In general, a lower clock frequency and a reduction in the number of circuits being clocked constitutes lower consumed power. PIC24HJXXXGPX06A/X08A/X10A devices can manage power consumption in four different ways: * * * * Clock frequency Instruction-based Sleep and Idle modes Software-controlled Doze mode Selective peripheral control in software Combinations of these methods can be used to selectively tailor an application's power consumption while still maintaining critical application features, such as timing-sensitive communications. 10.1 Clock Frequency and Clock Switching PIC24HJXXXGPX06A/X08A/X10A devices allow a wide range of clock frequencies to be selected under application control. If the system clock configuration is not locked, users can choose low-power or high-precision oscillators by simply changing the NOSC bits (OSCCON<10:8>). The process of changing a system clock during operation, as well as limitations to the process, are discussed in more detail in Section 9.0 "Oscillator Configuration". EXAMPLE 10-1: 10.2 Instruction-Based Power-Saving Modes PIC24HJXXXGPX06A/X08A/X10A devices have two special power-saving modes that are entered through the execution of a special PWRSAV instruction. Sleep mode stops clock operation and halts all code execution. Idle mode halts the CPU and code execution, but allows peripheral modules to continue operation. The assembly syntax of the PWRSAV instruction is shown in Example 10-1. Note: SLEEP_MODE and IDLE_MODE are constants defined in the assembler include file for the selected device. Sleep and Idle modes can be exited as a result of an enabled interrupt, WDT time-out or a device Reset. When the device exits these modes, it is said to "wake-up". 10.2.1 SLEEP MODE Sleep mode has these features: * The system clock source is shut down. If an on-chip oscillator is used, it is turned off. * The device current consumption is reduced to a minimum, provided that no I/O pin is sourcing current * The Fail-Safe Clock Monitor does not operate during Sleep mode since the system clock source is disabled * The LPRC clock continues to run in Sleep mode if the WDT is enabled * The WDT, if enabled, is automatically cleared prior to entering Sleep mode * Some device features or peripherals may continue to operate in Sleep mode. This includes items such as the input change notification on the I/O ports, or peripherals that use an external clock input. Any peripheral that requires the system clock source for its operation is disabled in Sleep mode. The device will wake-up from Sleep mode on any of these events: * Any interrupt source that is individually enabled * Any form of device Reset * A WDT time-out On wake-up from Sleep, the processor restarts with the same clock source that was active when Sleep mode was entered. PWRSAV INSTRUCTION SYNTAX PWRSAV #SLEEP_MODE PWRSAV #IDLE_MODE ; Put the device into SLEEP mode ; Put the device into IDLE mode 2009-2012 Microchip Technology Inc. DS70592D-page 133 PIC24HJXXXGPX06A/X08A/X10A 10.2.2 IDLE MODE Idle mode has these features: * The CPU stops executing instructions. * The WDT is automatically cleared. * The system clock source remains active. By default, all peripheral modules continue to operate normally from the system clock source, but can also be selectively disabled (see Section 10.4 "Peripheral Module Disable"). * If the WDT or FSCM is enabled, the LPRC also remains active. The device will wake from Idle mode on any of these events: * Any interrupt that is individually enabled. * Any device Reset. * A WDT time-out. On wake-up from Idle, the clock is reapplied to the CPU and instruction execution will begin (2-4 clock cycles later), starting with the instruction following the PWRSAV instruction, or the first instruction in the ISR. 10.2.3 INTERRUPTS COINCIDENT WITH POWER SAVE INSTRUCTIONS Any interrupt that coincides with the execution of a PWRSAV instruction is held off until entry into Sleep or Idle mode has completed. The device then wakes up from Sleep or Idle mode. 10.3 Doze Mode Generally, changing clock speed and invoking one of the power-saving modes are the preferred strategies for reducing power consumption. There may be circumstances, however, where this is not practical. For example, it may be necessary for an application to maintain uninterrupted synchronous communication, even while it is doing nothing else. Reducing system clock speed may introduce communication errors, while using a power-saving mode may stop communications completely. Doze mode is a simple and effective alternative method to reduce power consumption while the device is still executing code. In this mode, the system clock continues to operate from the same source and at the same speed. Peripheral modules continue to be clocked at the same speed, while the CPU clock speed is reduced. Synchronization between the two clock domains is maintained, allowing the peripherals to access the SFRs while the CPU executes code at a slower rate. DS70592D-page 134 Doze mode is enabled by setting the DOZEN bit (CLKDIV<11>). The ratio between peripheral and core clock speed is determined by the DOZE<2:0> bits (CLKDIV<14:12>). There are eight possible configurations, from 1:1 to 1:128, with 1:1 being the default setting. It is also possible to use Doze mode to selectively reduce power consumption in event-driven applications. This allows clock-sensitive functions, such as synchronous communications, to continue without interruption while the CPU idles, waiting for something to invoke an interrupt routine. Enabling the automatic return to full-speed CPU operation on interrupts is enabled by setting the ROI bit (CLKDIV<15>). By default, interrupt events have no effect on Doze mode operation. For example, suppose the device is operating at 20 MIPS and the CAN module has been configured for 500 kbps based on this device operating speed. If the device is now placed in Doze mode with a clock frequency ratio of 1:4, the CAN module continues to communicate at the required bit rate of 500 kbps, but the CPU now starts executing instructions at a frequency of 5 MIPS. 10.4 Peripheral Module Disable The Peripheral Module Disable (PMD) registers provide a method to disable a peripheral module by stopping all clock sources supplied to that module. When a peripheral is disabled via the appropriate PMD control bit, the peripheral is in a minimum power consumption state. The control and status registers associated with the peripheral are also disabled, so writes to those registers will have no effect and read values will be invalid. A peripheral module is only enabled if both the associated bit in the PMD register is cleared and the peripheral is supported by the specific dsPIC(R) DSC variant. If the peripheral is present in the device, it is enabled in the PMD register by default. Note: If a PMD bit is set, the corresponding module is disabled after a delay of 1 instruction cycle. Similarly, if a PMD bit is cleared, the corresponding module is enabled after a delay of 1 instruction cycle (assuming the module control registers are already configured to enable module operation). 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 11.0 I/O PORTS Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 10. "I/O Ports" (DS70193) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. All of the device pins (except VDD, VSS, MCLR and OSC1/CLKIN) are shared between the peripherals and the parallel I/O ports. All I/O input ports feature Schmitt Trigger inputs for improved noise immunity. 11.1 Parallel I/O (PIO) Ports A parallel I/O port that shares a pin with a peripheral is, in general, subservient to the peripheral. The peripheral's output buffer data and control signals are provided to a pair of multiplexers. The multiplexers select whether the peripheral or the associated port has ownership of the output data and control signals of the I/O pin. The logic also prevents "loop through", in FIGURE 11-1: which a port's digital output can drive the input of a peripheral that shares the same pin. Figure 11-1 shows how ports are shared with other peripherals and the associated I/O pin to which they are connected. When a peripheral is enabled and actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The I/O pin may be read, but the output driver for the parallel port bit will be disabled. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port. All port pins have three registers directly associated with their operation as digital I/O. The data direction register (TRISx) determines whether the pin is an input or an output. If the data direction bit is a `1', the pin is then an input. All port pins are defined as inputs after a Reset. Reads from the latch (LATx), read the latch. Writes to the latch, write the latch. Reads from the port (PORTx), read the port pins, while writes to the port pins, write the latch. Any bit and its associated data and control registers that are not valid for a particular device will be disabled. That means the corresponding LATx and TRISx registers and the port pins will read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nonetheless regarded as a dedicated port because there is no other competing source of outputs. An example is the INT4 pin. Note: The voltage on a digital input pin can be between -0.3V to 5.6V.

Input Data DS70592D-page 141 PIC24HJXXXGPX06A/X08A/X10A 11.2 Open-Drain Configuration 11.4 In addition to the PORT, LAT and TRIS registers for data control, some port pins can also be individually configured for either digital or open-drain output. This is controlled by the Open-Drain Control register, ODCx, associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain output. The open-drain feature allows the generation of outputs higher than VDD (e.g., 5V) on any desired 5V tolerant pins by using external pull-up resistors. The maximum open-drain voltage allowed is the same as the maximum VIH specification. See the "Pin Diagrams" section for the available pins and their functionality. 11.3 Configuring Analog Port Pins The use of the ADxPCFGH, ADxPCFGL and TRIS registers control the operation of the Analog-to-Digital port pins. The port pins that are desired as analog inputs must have their corresponding TRIS bit set (input). If the TRIS bit is cleared (output), the digital output level (VOH or VOL) is converted. Clearing any bit in the ADxPCFGH or ADxPCFGL register configures the corresponding bit to be an analog pin. This is also the Reset state of any I/O pin that has an analog (ANx) function associated with it. Note: In devices with two ADC modules, if the corresponding PCFG bit in either AD1PCFGH(L) and AD2PCFGH(L) is cleared, the pin is configured as an analog input. When reading the PORT register, all pins configured as analog input channels will read as cleared (a low level). I/O Port Write/Read Timing One instruction cycle is required between a port direction change or port write operation and a read operation of the same port. Typically, this instruction would be a NOP. 11.5 Input Change Notification The input change notification function of the I/O ports allows the PIC24HJXXXGPX06A/X08A/X10A devices to generate interrupt requests to the processor in response to a change-of-state on selected input pins. This feature is capable of detecting input change-of-states even in Sleep mode, when the clocks are disabled. Depending on the device pin count, there are up to 24 external signals (CN0 through CN23) that can be selected (enabled) for generating an interrupt request on a change-of-state. There are four control registers associated with the CN module. The CNEN1 and CNEN2 registers contain the CN interrupt enable (CNxIE) control bits for each of the CN input pins. Setting any of these bits enables a CN interrupt for the corresponding pins. Each CN pin also has a weak pull-up connected to it. The pull-ups act as a current source that is connected to the pin and eliminate the need for external resistors when push button or keypad devices are connected. The pull-ups are enabled separately using the CNPU1 and CNPU2 registers, which contain the weak pull-up enable (CNxPUE) bits for each of the CN pins. Setting any of the control bits enables the weak pull-ups for the corresponding pins. Note: Pull-ups on change notification pins should always be disabled whenever the port pin is configured as a digital output. Pins configured as digital inputs will not convert an analog input. Analog levels on any pin that is defined as a digital input (including the ANx pins) can cause the input buffer to consume current that exceeds the device specifications. Note: The voltage on an analog input pin can be between -0.3V to (VDD + 0.3 V).

PIC24HJXXXGPX06A/X08A/X10A 11.6 1. 2. In some cases, certain pins as defined in TABLE 24-9: "DC Characteristics: I/O Pin Input Specifications" under "Injection Current", have internal protection diodes to VDD and VSS. The term "Injection Current" is also referred to as "Clamp Current". On designated pins, with sufficient external current limiting precautions by the user, I/O pin input voltages are allowed to be greater or less than the data sheet absolute maximum ratings with nominal VDD with respect to the VSS and VDD supplies. Note that when the user application forward biases either of the high or low side internal input clamp diodes, that the resulting current being injected into the device that is clamped internally by the VDD and VSS power rails, may affect the ADC accuracy by four to six counts. I/O pins that are shared with any analog input pin, (i.e., ANx), are always analog pins by default after any reset. Consequently, any pin(s) configured as an analog input pin, automatically disables the digital input pin buffer. As such, any attempt to read a digital input pin will always return a `0' regardless of the digital logic level on the pin if the analog pin is configured. To use a pin as a digital I/O pin on a shared ANx pin, the user application needs to configure the analog pin configuration registers in the ADC module, (i.e., ADxPCFGL, AD1PCFGH), by setting the appropriate bit that corresponds to that I/O port pin to a `1'. On devices with more than one ADC, both analog pin configurations for both ADC modules must be configured as a digital I/O pin for that pin to function as a digital I/O pin. Note: 3. I/O Helpful Tips Although it is not possible to use a digital input pin when its analog function is enabled, it is possible to use the digital I/O output function, TRISx = 0x0, while the analog function is also enabled. However, this is not recommended, particularly if the analog input is connected to an external analog voltage source, which would create signal contention between the analog signal and the output pin driver. Most I/O pins have multiple functions. Referring to the device pin diagrams in the data sheet, the priorities of the functions allocated to any pins are indicated by reading the pin name from left-to-right. The left most function name takes precedence over any function to its right in the naming convention. For example: AN16/T2CK/T7CK/RC1. This indicates that AN16 is the highest priority in this example and will supersede all other functions to its right in the list. Those other functions to its right, even if enabled, would not work as long as any other function to its left was enabled. This rule applies to all of the functions listed for a given pin. 2009-2012 Microchip Technology Inc. 4. 5. Each CN pin has a configurable internal weak pull-up resistor. The pull-ups act as a current source connected to the pin, and eliminates the need for external resistors in certain applications. The internal pull-up is to ~(VDD-0.8) not VDD. This is still above the minimum VIH of CMOS and TTL devices. When driving LEDs directly, the I/O pin can source or sink more current than what is specified in the VOH/IOH and VOL/IOL DC characteristic specification. The respective IOH and IOL current rating only applies to maintaining the corresponding output at or above the VOH and at or below the VOL levels. However, for LEDs unlike digital inputs of an externally connected device, they are not governed by the same minimum VIH/VIL levels. An I/O pin output can safely sink or source any current less than that listed in the absolute maximum rating section of the data sheet. For example: VOH = 2.4v @ IOH = -8 mA and VDD = 3.3V The maximum output current sourced by any 8 mA I/O pin = 12 mA. LED source current < 12 mA is technically permitted. Refer to the VOH/IOH graphs in Section 24.0 "Electrical Characteristics" for additional information. 11.7 I/O Resources Many useful resources related to I/O are provided on the main product page of the Microchip web site for the devices listed in this data sheet.

PIC24HJXXXGPX06A/X08A/X10A 13.0 TIMER2/3, TIMER4/5, TIMER6/7 AND TIMER8/9 Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 11. "Timers" (DS70205) of the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The Timer2/3, Timer4/5, Timer6/7 and Timer8/9 modules are 32-bit timers, which can also be configured as four independent 16-bit timers with selectable operating modes. As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and Timer8/9 operate in three modes: * Two Independent 16-bit Timers (e.g., Timer2 and Timer3) with all 16-bit operating modes (except Asynchronous Counter mode) * Single 32-bit Timer * Single 32-bit Synchronous Counter They also support these features: * * * * * Timer Gate Operation Selectable Prescaler Settings Timer Operation during Idle and Sleep modes Interrupt on a 32-bit Period Register Match Time Base for Input Capture and Output Compare Modules (Timer2 and Timer3 only) * ADC1 Event Trigger (Timer2/3 only) * ADC2 Event Trigger (Timer4/5 only) Individually, all eight of the 16-bit timers can function as synchronous timers or counters. They also offer the features listed above, except for the event trigger; this is implemented only with Timer2/3. The operating modes and enabled features are determined by setting the appropriate bit(s) in the T2CON, T3CON, T4CON, T5CON, T6CON, T7CON, T8CON and T9CON registers. T2CON, T4CON, T6CON and T8CON are shown in generic form in Register 13-1. T3CON, T5CON, T7CON and T9CON are shown in Register 13-2. For 32-bit timer/counter operation, Timer2, Timer4, Timer6 or Timer8 is the least significant word; Timer3, Timer5, Timer7 or Timer9 is the most significant word of the 32-bit timers. Note: To configure Timer2/3, Timer4/5, Timer6/7 or Timer8/9 for 32-bit operation: 1. 2. 3. 4. 5. 6. Set the corresponding T32 control bit. Select the prescaler ratio for Timer2, Timer4, Timer6 or Timer8 using the TCKPS<1:0> bits. Set the Clock and Gating modes using the corresponding TCS and TGATE bits. Load the timer period value. PR3, PR5, PR7 or PR9 contains the most significant word of the value, while PR2, PR4, PR6 or PR8 contains the least significant word. If interrupts are required, set the interrupt enable bit, T3IE, T5IE, T7IE or T9IE. Use the priority bits, T3IP<2:0>, T5IP<2:0>, T7IP<2:0> or T9IP<2:0>, to set the interrupt priority. While Timer2, Timer4, Timer6 or Timer8 control the timer, the interrupt appears as a Timer3, Timer5, Timer7 or Timer9 interrupt. Set the corresponding TON bit. The timer value at any point is stored in the register pair, TMR3:TMR2, TMR5:TMR4, TMR7:TMR6 or TMR9:TMR8. TMR3, TMR5, TMR7 or TMR9 always contains the most significant word of the count, while TMR2, TMR4, TMR6 or TMR8 contains the least significant word. To configure any of the timers for individual 16-bit operation: 1. 2. 3. 4. 5. 6. 2009-2012 Microchip Technology Inc. For 32-bit operation, T3CON, T5CON, T7CON and T9CON control bits are ignored. Only T2CON, T4CON, T6CON and T8CON control bits are used for setup and control. Timer2, Timer4, Timer6 and Timer8 clock and gate inputs are utilized for the 32-bit timer modules, but an interrupt is generated with the Timer3, Timer5, Ttimer7 and Timer9 interrupt flags. Clear the T32 bit corresponding to that timer. Select the timer prescaler ratio using the TCKPS<1:0> bits. Set the Clock and Gating modes using the TCS and TGATE bits. Load the timer period value into the PRx register. If interrupts are required, set the interrupt enable bit, TxIE. Use the priority bits, TxIP<2:0>, to set the interrupt priority. Set the TON bit.

PIC24HJXXXGPX06A/X08A/X10A 14.0 INPUT CAPTURE Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F/PIC24H Family Reference Manual", Section 12.

Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The input capture module is useful in applications requiring frequency (period) and pulse measurement. The PIC24HJXXXGPX06A/X08A/X10A devices support up to eight input capture channels. * Capture timer value on every edge (rising and falling) * Prescaler Capture Event modes: - Capture timer value on every 4th rising edge of input at ICx pin - Capture timer value on every 16th rising edge of input at ICx pin Each input capture channel can select between one of two 16-bit timers (Timer2 or Timer3) for the time base. The selected timer can use either an internal or external clock. Other operational features include: * Device wake-up from capture pin during CPU Sleep and Idle modes * Interrupt on input capture event * 4-word FIFO buffer for capture values - Interrupt optionally generated after 1, 2, 3 or 4 buffer locations are filled * Input capture can also be used to provide additional sources of external interrupts. Note: The input capture module captures the 16-bit value of the selected Time Base register when an event occurs at the ICx pin. The events that cause a capture event are listed below in three categories: Only IC1 and IC2 can trigger a DMA data transfer. If DMA data transfers are required, the FIFO buffer size must be set to 1 (ICI<1:0> = 00). * Simple Capture Event modes: - Capture timer value on every falling edge of input at ICx pin - Capture timer value on every rising edge of input at ICx pin FIGURE 14-1: INPUT CAPTURE BLOCK DIAGRAM From 16-bit Timers TMRy TMRz 16 16 1 Edge Detection Logic and Clock Synchronizer Prescaler Counter (1, 4, 16) ICx Pin ICM<2:0> (ICxCON<2:0>) Mode Select ICTMR (ICxCON<7>) FIFO 3 0 FIFO R/W Logic ICOV, ICBNE (ICxCON<4:3>) ICxBUF ICxI<1:0> ICxCON Interrupt Logic System Bus Set Flag ICxIF (in IFSn Register) Note: An `x' in a signal, register or bit name denotes the number of the capture channel. 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 16.0 SERIAL PERIPHERAL INTERFACE (SPI) Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F/PIC24H Family Reference Manual", Section 18. "Serial Peripheral Interface (SPI)" (DS70206), which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The Serial Peripheral Interface (SPI) module is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be serial EEPROMs, shift registers, display drivers, Analog-to-Digital converters, etc. The SPI module is compatible with SPI and SIOP from Motorola(R). Note: In this section, the SPI modules are referred to together as SPIx, or separately as SPI1 and SPI2. Special Function Registers will follow a similar notation. For example, SPIxCON refers to the control register for the SPI1 or SPI2 module. Each SPI module consists of a 16-bit shift register, SPIxSR (where x = 1 or 2), used for shifting data in and out, and a buffer register, SPIxBUF. A control register, SPIxCON, configures the module. Additionally, a status register, SPIxSTAT, indicates various status conditions. The serial interface consists of 4 pins: SDIx (serial data input), SDOx (serial data output), SCKx (shift clock input or output), and SSx (active-low slave select). In Master mode operation, SCK is a clock output but in Slave mode, it is a clock input.

In Frame mode, if there is a possibility that the master may not be initialized before the slave: a) If FRMPOL (SPIxCON2<13>) = 1, use a pull-down resistor on SSx. b) If FRMPOL = 0, use a pull-up resistor on SSx. Note: 2. 5. This will insure that during power-up and initialization the master/slave will not lose sync due to an errant SCK transition that would cause the slave to accumulate data shift errors for both transmit and receive appearing as corrupted data.

In Frame mode, SCKx is continuous and the Frame sync pulse is active on the SSx pin, which indicates the start of a data frame. Note: 4. 16.2 This insures that the first frame transmission after initialization is not shifted or corrupted. In non-framed 3-wire mode, (i.e., not using SSx from a master): a) If CKP (SPIxCON1<6>) = 1, always place a pull-up resistor on SSx. b) If CKP = 0, always place a pull-down resistor on SSx. Note: 3. SPI Helpful Tips Not all third-party devices support Frame mode timing. Refer to the SPI electrical characteristics for details. In Master mode only, set the SMP bit (SPIxCON1<9>) to a `1' for the fastest SPI data rate possible. The SMP bit can only be set at the same time or after the MSTEN bit (SPIxCON1<5>) is set. To avoid invalid slave read data to the master, the user's master software must guarantee enough time for slave software to fill its write buffer before the user application initiates a master write/read cycle. It is always advisable to preload the SPIxBUF transmit register in advance of the next master transaction cycle. SPIxBUF is transferred to the SPI shift register and is empty once the data transmission begins. DS70592D-page 160 2009-2012 Microchip Technology Inc.

Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The Universal Asynchronous Receiver Transmitter (UART) module is one of the serial I/O modules available in the PIC24HJXXXGPX06A/X08A/X10A device family. The UART is a full-duplex asynchronous system that can communicate with peripheral devices, such as personal computers, LIN, RS-232 and RS-485 interfaces. The module also supports a hardware flow control option with the UxCTS and UxRTS pins and also includes an IrDA(R) encoder and decoder. The primary features of the UART module are: FIGURE 18-1: * Full-Duplex, 8 or 9-bit Data Transmission through the UxTX and UxRX pins * Even, Odd or No Parity Options (for 8-bit data) * One or Two Stop bits * Hardware Flow Control Option with UxCTS and UxRTS pins * Fully Integrated Baud Rate Generator with 16-bit Prescaler * Baud rates ranging from 10 Mbps to 38 bps at 40 MIPS * 4-deep First-In-First-Out (FIFO) Transmit Data Buffer * 4-Deep FIFO Receive Data Buffer * Parity, Framing and Buffer Overrun Error Detection * Support for 9-bit mode with Address Detect (9th bit = 1) * Transmit and Receive Interrupts * A Separate Interrupt for all UART Error Conditions * Loopback mode for Diagnostic Support * Support for Sync and Break Characters * Supports Automatic Baud Rate Detection * IrDA(R) Encoder and Decoder Logic * 16x Baud Clock Output for IrDA(R) Support A simplified block diagram of the UART is shown in Figure 18-1. The UART module consists of the key important hardware elements: * Baud Rate Generator * Asynchronous Transmitter * Asynchronous Receiver UART SIMPLIFIED BLOCK DIAGRAM Baud Rate Generator IrDA(R) Hardware Flow Control UxRTS/BCLK UxCTS UART Receiver UxRX UART Transmitter UxTX Note 1: Both UART1 and UART2 can trigger a DMA data transfer. If U1TX, U1RX, U2TX or U2RX is selected as a DMA IRQ source, a DMA transfer occurs when the U1TXIF, U1RXIF, U2TXIF or U2RXIF bit gets set as a result of a UART1 or UART2 transmission or reception. 2: If DMA transfers are required, the UART TX/RX FIFO buffer must be set to a size of 1 byte/word (i.e., UTXISEL<1:0> = 00 and URXISEL<1:0> = 00). 2009-2012 Microchip Technology Inc. DS70592D-page 173 PIC24HJXXXGPX06A/X08A/X10A 18.1 1. 2. UART Helpful Tips In multi-node direct-connect UART networks, UART receive inputs react to the complementary logic level defined by the URXINV bit (UxMODE<4>), which defines the idle state, the default of which is logic high, (i.e., URXINV = 0). Because remote devices do not initialize at the same time, it is likely that one of the devices, because the RX line is floating, will trigger a start bit detection and will cause the first byte received after the device has been initialized to be invalid. To avoid this situation, the user should use a pull-up or pull-down resistor on the RX pin depending on the value of the URXINV bit. a) If URXINV = 0, use a pull-up resistor on the RX pin. b) If URXINV = 1, use a pull-down resistor on the RX pin. The first character received on a wake-up from Sleep mode caused by activity on the UxRX pin of the UART module will be invalid. In Sleep mode, peripheral clocks are disabled. By the time the oscillator system has restarted and stabilized from Sleep mode, the baud rate bit sampling clock relative to the incoming UxRX bit timing is no longer synchronized, resulting in the first character being invalid. This is to be expected.

PIC24HJXXXGPX06A/X08A/X10A 19.0 ENHANCED CAN (ECANTM) MODULE Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F/PIC24H Family Reference Manual", Section 21. "Enhanced Controller Area Network (ECANTM)" (DS70185), which is available from the Microchip web site (www.microchip.com). 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. 19.1 Overview The Enhanced Controller Area Network (ECANTM) module is a serial interface, useful for communicating with other CAN modules or microcontroller devices. This interface/protocol was designed to allow communications within noisy environments. The PIC24HJXXXGPX06A/X08A/X10A devices contain up to two ECAN modules. The CAN module is a communication controller implementing the CAN 2.0 A/B protocol, as defined in the BOSCH specification. The module will support CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B Active versions of the protocol. The module implementation is a full CAN system. The CAN specification is not covered within this data sheet. The reader may refer to the BOSCH CAN specification for further details. The module features are as follows: * Implementation of the CAN protocol, CAN 1.2, CAN 2.0A and CAN 2.0B * Standard and extended data frames * 0-8 bytes data length * Programmable bit rate up to 1 Mbit/sec * Automatic response to remote transmission requests * Up to 8 transmit buffers with application specified prioritization and abort capability (each buffer may contain up to 8 bytes of data) * Up to 32 receive buffers (each buffer may contain up to 8 bytes of data) * Up to 16 full (standard/extended identifier) acceptance filters * 3 full acceptance filter masks * DeviceNetTM addressing support * Programmable wake-up functionality with integrated low-pass filter * Programmable Loopback mode supports self-test operation 2009-2012 Microchip Technology Inc. * Signaling via interrupt capabilities for all CAN receiver and transmitter error states * Programmable clock source * Programmable link to input capture module (IC2 for both CAN1 and CAN2) for time-stamping and network synchronization * Low-power Sleep and Idle mode The CAN bus module consists of a protocol engine and message buffering/control. The CAN protocol engine handles all functions for receiving and transmitting messages on the CAN bus. Messages are transmitted by first loading the appropriate data registers. Status and errors can be checked by reading the appropriate registers. Any message detected on the CAN bus is checked for errors and then matched against filters to see if it should be received and stored in one of the receive registers. 19.2 Frame Types The CAN module transmits various types of frames which include data messages, remote transmission requests and as other frames that are automatically generated for control purposes. The following frame types are supported: * Standard Data Frame: A standard data frame is generated by a node when the node wishes to transmit data. It includes an 11-bit standard identifier (SID) but not an 18-bit extended identifier (EID). * Extended Data Frame: An extended data frame is similar to a standard data frame but includes an extended identifier as well. * Remote Frame: It is possible for a destination node to request the data from the source. For this purpose, the destination node sends a remote frame with an identifier that matches the identifier of the required data frame. The appropriate data source node will then send a data frame as a response to this remote request. * Error Frame: An error frame is generated by any node that detects a bus error. An error frame consists of two fields: an error flag field and an error delimiter field. * Overload Frame: An overload frame can be generated by a node as a result of two conditions. First, the node detects a dominant bit during interframe space which is an illegal condition. Second, due to internal conditions, the node is not yet able to start reception of the next message. A node may generate a maximum of 2 sequential overload frames to delay the start of the next message. * Interframe Space: Interframe space separates a proceeding frame (of whatever type) from a following data or remote frame.

DS70592D-page 180 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 19.3 Modes of Operation The CAN module can operate in one of several operation modes selected by the user. These modes include: * * * * * * Initialization Mode Disable Mode Normal Operation Mode Listen Only Mode Listen All Messages Mode Loopback Mode Modes are requested by setting the REQOP<2:0> bits (CiCTRL1<10:8>). Entry into a mode is Acknowledged by monitoring the OPMODE<2:0> bits (CiCTRL1<7:5>). The module will not change the mode and the OPMODE bits until a change in mode is acceptable, generally during bus Idle time, which is defined as at least 11 consecutive recessive bits. 19.3.1 INITIALIZATION MODE In the Initialization mode, the module will not transmit or receive. The error counters are cleared and the interrupt flags remain unchanged. The programmer will have access to Configuration registers that are access restricted in other modes. The module will protect the user from accidentally violating the CAN protocol through programming errors. All registers which control the configuration of the module cannot be modified while the module is on-line. The CAN module will not be allowed to enter the Configuration mode while a transmission is taking place. The Configuration mode serves as a lock to protect the following registers. * * * * * All Module Control Registers Baud Rate and Interrupt Configuration Registers Bus Timing Registers Identifier Acceptance Filter Registers Identifier Acceptance Mask Registers 19.3.2 DISABLE MODE In Disable mode, the module will not transmit or receive. The module has the ability to set the WAKIF bit due to bus activity, however, any pending interrupts will remain and the error counters will retain their value. If the REQOP<2:0> bits (CiCTRL1<10:8>) = 001, the module will enter the Module Disable mode. If the module is active, the module will wait for 11 recessive bits on the CAN bus, detect that condition as an Idle bus, then accept the module disable command. When the OPMODE<2:0> bits (CiCTRL1<7:5>) = 001, that indicates whether the module successfully went into Module Disable mode. The I/O pins will revert to normal I/O function when the module is in the Module Disable mode. 2009-2012 Microchip Technology Inc. The module can be programmed to apply a low-pass filter function to the CiRX input line while the module or the CPU is in Sleep mode. The WAKFIL bit (CiCFG2<14>) enables or disables the filter. Note: 19.3.3 Typically, if the CAN module is allowed to transmit in a particular mode of operation and a transmission is requested immediately after the CAN module has been placed in that mode of operation, the module waits for 11 consecutive recessive bits on the bus before starting transmission. If the user application switches to Disable mode within this 11-bit period, the transmission is then aborted and the corresponding TXABT bit is set and the TXREQ bit is cleared. NORMAL OPERATION MODE Normal Operation mode is selected when REQOP<2:0> = 000. In this mode, the module is activated and the I/O pins will assume the CAN bus functions. The module will transmit and receive CAN bus messages via the CiTX and CiRX pins. 19.3.4 LISTEN ONLY MODE If the Listen Only mode is activated, the module on the CAN bus is passive. The transmitter buffers revert to the port I/O function. The receive pins remain inputs. For the receiver, no error flags or Acknowledge signals are sent. The error counters are deactivated in this state. The Listen Only mode can be used for detecting the baud rate on the CAN bus. To use this, it is necessary that there are at least two further nodes that communicate with each other. 19.3.5 LISTEN ALL MESSAGES MODE The module can be set to ignore all errors and receive any message. The Listen All Messages mode is activated by setting REQOP<2:0> = `111'. In this mode, the data which is in the message assembly buffer, until the time an error occurred, is copied in the receive buffer and can be read via the CPU interface. 19.3.6 LOOPBACK MODE If the Loopback mode is activated, the module will connect the internal transmit signal to the internal receive signal at the module boundary. The transmit and receive pins revert to their port I/O function.

PIC24HJXXXGPX06A/X08A/X10A 20.0 10-BIT/12-BIT ANALOG-TO-DIGITAL CONVERTER (ADC) Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A family of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the "dsPIC33F/PIC24H Family Reference Manual", Section 16. "Analog-to-Digital Converter (ADC)" (DS70183), which is available from the Microchip web site (www.microchip.com). Depending on the particular device pinout, the Analog-to-Digital Converter can have up to 32 analog input pins, designated AN0 through AN31. In addition, there are two analog input pins for external voltage reference connections. These voltage reference inputs may be shared with other analog input pins. The actual number of analog input pins and external voltage reference input configuration will depend on the specific device. A block diagram of the Analog-to-Digital Converter is shown in Figure 20-1. 20.2 The following configuration steps should be performed. 1. 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The PIC24HJXXXGPX06A/X08A/X10A devices have up to 32 Analog-to-Digital input channels. These devices also have up to 2 Analog-to-Digital converter modules (ADCx, where `x' = 1 or 2), each with its own set of Special Function Registers. The AD12B bit (ADxCON1<10>) allows each of the ADC modules to be configured by the user as either a 10-bit, 4-sample/hold ADC (default configuration) or a 12-bit, 1-sample/hold ADC. Note: 20.1 The ADC module needs to be disabled before modifying the AD12B bit. Key Features Analog-to-Digital Initialization 2. Configure the ADC module: a) Select port pins as analog inputs (ADxPCFGH<15:0> or ADxPCFGL<15:0>) b) Select voltage reference source to match expected range on analog inputs (ADxCON2<15:13>) c) Select the analog conversion clock to match desired data rate with processor clock (ADxCON3<7:0>) d) Determine how many S/H channels will be used (ADxCON2<9:8> and ADxPCFGH<15:0> or ADxPCFGL<15:0>) e) Select the appropriate sample/conversion sequence (ADxCON1<7:5> and ADxCON3<12:8>) f) Select how conversion results are presented in the buffer (ADxCON1<9:8>) g) Turn on the ADC module (ADxCON1<15>) Configure ADC interrupt (if required): a) Clear the ADxIF bit b) Select ADC interrupt priority The 10-bit ADC configuration has the following key features: 20.3 * * * * * If more than one conversion result needs to be buffered before triggering an interrupt, DMA data transfers can be used. Both ADC1 and ADC2 can trigger a DMA data transfer. If ADC1 or ADC2 is selected as the DMA IRQ source, a DMA transfer occurs when the AD1IF or AD2IF bit gets set as a result of an ADC1 or ADC2 sample conversion sequence. * * * * * Successive Approximation (SAR) conversion Conversion speeds of up to 1.1 Msps Up to 32 analog input pins External voltage reference input pins Simultaneous sampling of up to four analog input pins Automatic Channel Scan mode Selectable conversion trigger source Selectable Buffer Fill modes Two result alignment options (signed/unsigned) Operation during CPU Sleep and Idle modes The 12-bit ADC configuration supports all the above features, except: * In the 12-bit configuration, conversion speeds of up to 500 ksps are supported * There is only 1 sample/hold amplifier in the 12-bit configuration, so simultaneous sampling of multiple channels is not supported. 2009-2012 Microchip Technology Inc. ADC and DMA The SMPI<3:0> bits (ADxCON2<5:2>) are used to select how often the DMA RAM buffer pointer is incremented. The ADDMABM bit (ADxCON1<12>) determines how the conversion results are filled in the DMA RAM buffer area being used for ADC. If this bit is set, DMA buffers are written in the order of conversion. The module will provide an address to the DMA channel that is the same as the address used for the non-DMA stand-alone buffer. If the ADDMABM bit is cleared, the DMA buffers are written in Scatter/Gather mode. The module will provide a scatter/gather address to the DMA channel, based on the index of the analog input and the size of the DMA buffer.

DS70592D-page 209 PIC24HJXXXGPX06A/X08A/X10A 20.4 1. 2. 3. 4. 5. ADC Helpful Tips The SMPI<3:0> (AD1CON2<5:2>) control bits: a) Determine when the ADC interrupt flag is set and an interrupt is generated if enabled. b) When the CSCNA bit (AD1CON2<10>) is set to `1', determines when the ADC analog scan channel list defined in the AD1CSSL/ AD1CSSH registers starts over from the beginning. c) On devices without a DMA peripheral, determines when ADC result buffer pointer to ADC1BUF0-ADC1BUFF, gets reset back to the beginning at ADC1BUF0. On devices without a DMA module, the ADC has 16 result buffers. ADC conversion results are stored sequentially in ADC1BUF0-ADC1BUFF regardless of which analog inputs are being used subject to the SMPI<3:0> bits (AD1CON2<5:2>) and the condition described in 1c above. There is no relationship between the ANx input being measured and which ADC buffer (ADC1BUF0-ADC1BUFF) that the conversion results will be placed in. On devices with a DMA module, the ADC module has only 1 ADC result buffer, (i.e., ADC1BUF0), per ADC peripheral and the ADC conversion result must be read either by the CPU or DMA controller before the next ADC conversion is complete to avoid overwriting the previous value. The DONE bit (AD1CON1<0>) is only cleared at the start of each conversion and is set at the completion of the conversion, but remains set indefinitely even through the next sample phase until the next conversion begins. If application code is monitoring the DONE bit in any kind of software loop, the user must consider this behavior because the CPU code execution is faster than the ADC. As a result, in manual sample mode, particularly where the users code is setting the SAMP bit (AD1CON1<1>), the DONE bit should also be cleared by the user application just before setting the SAMP bit. On devices with two ADC modules, the ADCxPCFG registers for both ADC modules must be set to a logic `1' to configure a target I/O pin as a digital I/O pin. Failure to do so means that any alternate digital input function will always see only a logic `0' as the digital input buffer is held in Disable mode.

PIC24HJXXXGPX06A/X08A/X10A 21.0 SPECIAL FEATURES 21.1 Configuration Bits PIC24HJXXXGPX06A/X08A/X10A devices provide nonvolatile memory implementation for device configuration bits. Refer to Section 25. "Device Configuration" (DS70194) of the "dsPIC33F/PIC24H Family Reference Manual", for more information on this implementation. Note 1: This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A families of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 23. "CodeGuardTM Security" (DS70199), Section 24. "Programming and Diagnostics" (DS70207), and Section 25. "Device Configuration" (DS70194) in the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The Configuration bits can be programmed (read as `0'), or left unprogrammed (read as `1'), to select various device configurations. These bits are mapped starting at program memory location 0xF80000. The device Configuration register map is shown in Table 21-1. The individual Configuration bit descriptions for the Configuration registers are shown in Table 21-2. 2: Some registers and associated bits described in this section may not be available on all devices. Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. Note that address 0xF80000 is beyond the user program memory space. In fact, it belongs to the configuration memory space (0x800000-0xFFFFFF), which can only be accessed using table reads and table writes. PIC24HJXXXGPX06A/X08A/X10A devices include several features intended to maximize application flexibility and reliability, and minimize cost through elimination of external components.

Description DS70592D-page 225 PIC24HJXXXGPX06A/X08A/X10A 21.2 On-Chip Voltage Regulator All of the PIC24HJXXXGPX06A/X08A/X10A devices power their core digital logic at a nominal 2.5V. This may create an issue for designs that are required to operate at a higher typical voltage, such as 3.3V. To simplify system design, all devices in the PIC24HJXXXGPX06A/X08A/X10A family incorporate an on-chip regulator that allows the device to run its core logic from VDD. The regulator provides power to the core from the other VDD pins. The regulator requires that a low-ESR (less than 5 ohms) capacitor (such as tantalum or ceramic) be connected to the VCAP pin (Figure 21-1). This helps to maintain the stability of the regulator. The recommended value for the filter capacitor is provided in Table 24-13 of Section 24.1 "DC Characteristics". It is important for the low-ESR capacitor to be placed as close as possible to the VCAP pin. Note: On a POR, it takes approximately 20 s for the on-chip voltage regulator to generate an output voltage. During this time, designated as TSTARTUP, code execution is disabled. TSTARTUP is applied every time the device resumes operation after any power-down. FIGURE 21-1: ON-CHIP VOLTAGE REGULATOR CONNECTIONS(1,2,3) 21.3 Brown-out Reset (BOR) The BOR (Brown-out Reset) module is based on an internal voltage reference circuit that monitors the regulated voltage VCAP. The main purpose of the BOR module is to generate a device Reset when a brown-out condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (i.e., missing portions of the AC cycle waveform due to bad power transmission lines or voltage sags due to excessive current draw when a large inductive load is turned on). A BOR will generate a Reset pulse which will reset the device. The BOR will select the clock source, based on the device Configuration bit values (FNOSC<2:0> and POSCMD<1:0>). Furthermore, if an oscillator mode is selected, the BOR will activate the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, the clock will be held until the LOCK bit (OSCCON<5>) is `1'. Concurrently, the PWRT time-out (TPWRT) will be applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, a nominal delay of TFSCM = 100 is applied. The total delay in this case is TFSCM. The BOR Status bit (RCON<1>) will be set to indicate that a BOR has occurred. The BOR circuit continues to operate while in Sleep or Idle modes and will reset the device should VDD fall below the BOR threshold voltage. 3.3V PIC24H VDD VCAP CEFC 10 F Note 1: 2: 3: VSS These are typical operating voltages. Refer to Table 24-13 located in Section 24.1 "DC Characteristics" for the full operating ranges of VDD and VCAP. It is important for the low-ESR capacitor to be placed as close as possible to the VCAP pin. Typical VCAP pin voltage = 2.5V when VDD VDDMIN. DS70592D-page 226 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 21.4 Watchdog Timer (WDT) For PIC24HJXXXGPX06A/X08A/X10A devices, the WDT is driven by the LPRC oscillator. When the WDT is enabled, the clock source is also enabled. The nominal WDT clock source from LPRC is 32 kHz. This feeds a prescaler than can be configured for either 5-bit (divide-by-32) or 7-bit (divide-by-128) operation. The prescaler is set by the WDTPRE Configuration bit. With a 32 kHz input, the prescaler yields a nominal WDT time-out period (TWDT) of 1 ms in 5-bit mode, or 4 ms in 7-bit mode. A variable postscaler divides down the WDT prescaler output and allows for a wide range of time-out periods. The postscaler is controlled by the WDTPOST<3:0> Configuration bits (FWDT<3:0>) which allow the selection of a total of 16 settings, from 1:1 to 1:32,768. Using the prescaler and postscaler, time-out periods ranging from 1 ms to 131 seconds can be achieved. The WDT, prescaler and postscaler are reset: * On any device Reset * On the completion of a clock switch, whether invoked by software (i.e., setting the OSWEN bit after changing the NOSC bits) or by hardware (i.e., Fail-Safe Clock Monitor) * When a PWRSAV instruction is executed (i.e., Sleep or Idle mode is entered) * When the device exits Sleep or Idle mode to resume normal operation * By a CLRWDT instruction during normal execution FIGURE 21-2: If the WDT is enabled, it will continue to run during Sleep or Idle modes. When the WDT time-out occurs, the device will wake the device and code execution will continue from where the PWRSAV instruction was executed. The corresponding SLEEP or IDLE bits (RCON<3,2>) will need to be cleared in software after the device wakes up. The WDT flag bit, WDTO (RCON<4>), is not automatically cleared following a WDT time-out. To detect subsequent WDT events, the flag must be cleared in software. Note: The CLRWDT and PWRSAV instructions clear the prescaler and postscaler counts when executed. The WDT is enabled or disabled by the FWDTEN Configuration bit in the FWDT Configuration register. When the FWDTEN Configuration bit is set, the WDT is always enabled. The WDT can be optionally controlled in software when the FWDTEN Configuration bit has been programmed to `0'. The WDT is enabled in software by setting the SWDTEN control bit (RCON<5>). The SWDTEN control bit is cleared on any device Reset. The software WDT option allows the user to enable the WDT for critical code segments and disable the WDT during non-critical segments for maximum power savings. Note: If the WINDIS bit (FWDT<6>) is cleared, the CLRWDT instruction should be executed by the application software only during the last 1/4 of the WDT period. This CLRWDT window can be determined by using a timer. If a CLRWDT instruction is executed before this window, a WDT Reset occurs.

Detailed information on the interface will be provided in future revisions of the document. Note: 21.6 For further information, refer to the dsPIC33F/PIC24H Family Reference Manual", Section 24. "Programming and Diagnostics" (DS70207), which is available from the Microchip web site (www.microchip.com). Code Protection and CodeGuardTM Security The PIC24H product families offer advanced implementation of CodeGuardTM Security. CodeGuard Security enables multiple parties to securely share resources (memory, interrupts and peripherals) on a single chip. This feature helps protect individual Intellectual Property in collaborative system designs. When coupled with software encryption libraries, CodeGuard Security can be used to securely update Flash even when multiple IP are resident on the single chip. The code protection features vary depending on the actual PIC24H implemented. The following sections provide an overview these features. The code protection features are controlled by the Configuration registers: FBS, FSS and FGS. Note: For further information, refer to the "dsPIC33F/PIC24H Family Reference Manual", Section 23. "CodeGuardTM Security" (DS70239), which is available from the Microchip web site (www.microchip.com). DS70592D-page 228 21.7 In-Circuit Serial Programming Programming Capability PIC24HJXXXGPX06A/X08A/X10A family digital signal controllers can be serially programmed while in the end application circuit. This is simply done with two lines for clock and data and three other lines for power, ground and the programming sequence. This allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. This also allows the most recent firmware or a custom firmware, to be programmed. Please refer to the "dsPIC33F/PIC24H Flash Programming Specification" (DS70152) document for details about ICSP programming capability. Any one out of three pairs of programming clock/data pins may be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3 21.8 In-Circuit Debugger When MPLAB(R) ICD 3 is selected as a debugger, the in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with MPLAB IDE. Debugging functionality is controlled through the PGECx (Emulation/Debug Clock) and PGEDx (Emulation/Debug Data) pin functions. Any one out of three pairs of debugging clock/data pins may be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3 To use the in-circuit debugger function of the device, the design must implement ICSP programming capability connections to MCLR, VDD, VSS and the PGEDx/ PGECx pin pair. In addition, when the feature is enabled, some of the resources are not available for general use. These resources include the first 80 bytes of data RAM and two I/O pins. 2009-2012 Microchip Technology Inc. PIC24HJXXXGPX06A/X08A/X10A 22.0 Note: INSTRUCTION SET SUMMARY This data sheet summarizes the features of the PIC24HJXXXGPX06A/X08A/X10A families of devices. However, it is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section in the "dsPIC33F/PIC24H Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The PIC24H instruction set is identical to that of the PIC24F, and is a subset of the dsPIC30F/33F instruction set. Most instructions are a single program memory word (24 bits). Only three instructions require two program memory locations. Each single-word instruction is a 24-bit word, divided into an 8-bit opcode, which specifies the instruction type and one or more operands, which further specify the operation of the instruction. The instruction set is highly orthogonal and is grouped into five basic categories: * * * * * Word or byte-oriented operations Bit-oriented operations Literal operations DSP operations Control operations Table 22-1 shows the general symbols used in describing the instructions. The PIC24H instruction set summary in Table 22-2 lists all the instructions, along with the status flags affected by each instruction. Most word or byte-oriented W register instructions (including barrel shift instructions) have three operands: * The first source operand which is typically a register `Wb' without any address modifier * The second source operand which is typically a register `Ws' with or without an address modifier * The destination of the result which is typically a register `Wd' with or without an address modifier However, word or byte-oriented file register instructions have two operands: * The file register specified by the value `f' * The destination, which could either be the file register `f' or the W0 register, which is denoted as `WREG' Most bit-oriented instructions (including simple rotate/shift instructions) have two operands: * The W register (with or without an address modifier) or file register (specified by the value of `Ws' or `f') * The bit in the W register or file register (specified by a literal value or indirectly by the contents of register `Wb') The literal instructions that involve data movement may use some of the following operands: * A literal value to be loaded into a W register or file register (specified by the value of `k') * The W register or file register where the literal value is to be loaded (specified by `Wb' or `f') However, literal instructions that involve arithmetic or logical operations use some of the following operands: * The first source operand which is a register `Wb' without any address modifier * The second source operand which is a literal value * The destination of the result (only if not the same as the first source operand) which is typically a register `Wd' with or without an address modifier The control instructions may use some of the following operands: * A program memory address * The mode of the table read and table write instructions All instructions are a single word, except for certain double word instructions, which were made double word instructions so that all the required information is available in these 48 bits. In the second word, the 8 MSbs are `0's. If this second word is executed as an instruction (by itself), it will execute as a NOP. Most single-word instructions are executed in a single instruction cycle, unless a conditional test is true, or the program counter is changed as a result of the instruction. In these cases, the execution takes two instruction cycles with the additional instruction cycle(s) executed as a NOP. Notable exceptions are the BRA (unconditional/computed branch), indirect CALL/GOTO, all table reads and writes and RETURN/RETFIE instructions, which are single-word instructions but take two or three cycles. Certain instructions that involve skipping over the subsequent instruction require either two or three cycles if the skip is performed, depending on whether the instruction being skipped is a single-word or double word instruction. Moreover, double word moves require two cycles. The double word instructions execute in two instruction cycles. Note: 2009-2012 Microchip Technology Inc.

PIC24HJXXXGPX06A/X08A/X10A 25.0 HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS This section provides an overview of PIC24HJXXXGPX06A/X08A/X10A electrical characteristics for devices operating in an ambient temperature range of -40C to +150C. The specifications between -40C to +150C are identical to those shown in Section 24.0 "Electrical Characteristics" for operation between -40C to +125C, with the exception of the parameters listed in this section. Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in Section 24.0 "Electrical Characteristics" is the Industrial and Extended temperature equivalent of HDC10. Absolute maximum ratings for the PIC24HJXXXGPX06A/X08A/X10A high temperature devices are listed below. Exposure to these maximum rating conditions for extended periods can affect device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in the operation listings of this specification is not implied. Absolute Maximum Ratings (See Note 1 ) Ambient temperature under bias(4) .........................................................................................................-40C to +150C Storage temperature .............................................................................................................................. -65C to +160C Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V Voltage on any pin that is not 5V tolerant with respect to VSS(5) .................................................... -0.3V to (VDD + 0.3V) Voltage on any 5V tolerant pin with respect to VSS when VDD < 3.0V(5) ....................................... -0.3V to (VDD + 0.3V) Voltage on any 5V tolerant pin with respect to VSS when VDD 3.0V(5) .................................................... -0.3V to 5.6V Voltage on VCAP with respect to VSS ...................................................................................................... 2.25V to 2.75V Maximum current out of VSS pin .............................................................................................................................60 mA Maximum current into VDD pin(2) .............................................................................................................................60 mA Maximum junction temperature............................................................................................................................. +155C Maximum current sourced/sunk by any 2x I/O pin(3) ................................................................................................2 mA Maximum current sourced/sunk by any 4x I/O pin(3) ................................................................................................4 mA Maximum current sourced/sunk by any 8x I/O pin(3) ................................................................................................8 mA Maximum current sunk by all ports combined ........................................................................................................10 mA Maximum current sourced by all ports combined(2) ................................................................................................10 mA Note 1: Stresses above those listed under "Absolute Maximum Ratings" can cause permanent damage to the device. This is a stress rating only, and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods can affect device reliability. 2: Maximum allowable current is a function of device maximum power dissipation (see Table 25-2). 3: Unlike devices at 125C and below, the specifications in this section also apply to the CLKOUT, VREF+, VREF-, SCLx, SDAx, PGECx, and PGEDx pins. 4: AEC-Q100 reliability testing for devices intended to operate at 150C is 1,000 hours. Any design in which the total operating time from 125C to 150C will be greater than 1,000 hours is not warranted without prior written approval from Microchip Technology Inc. 5: Refer to the "Pin Diagrams" section for 5V tolerant pins. 2009-2012 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
