Consider the following criteria when using decoupling capacitors: Note 1: This data sheet summarizes the features of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section of the "dsPIC33E/PIC24E 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. 2.1 Decoupling Capacitors Basic Connection Requirements Getting started with the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 families of 16-bit DSC and microcontrollers 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") * 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 to use ceramic capacitors. * 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, above 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: * VUSB pin is used when utilizing the USB module. If the USB module is not used, VUSB must be connected to VDD. * VREF+/VREF- pins is 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.

Place the components as shown in Figure 2-2 within one-quarter inch (6 mm) from the MCLR pin. FIGURE 2-2: 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 DSCs 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 pin 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.

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 (< 1 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 greater than 4.7 F (10 F is recommended), 16V connected to ground. The type can be ceramic or tantalum. See Section 32.0 "Electrical Characteristics" for additional information. The placement of this capacitor should be close to the VCAP. It is recommended that the trace length not exceeds one-quarter inch (6 mm). See Section 29.2 "On-Chip Voltage Regulator" for details. DS70616C-page 28 Preliminary (c) 2009-2011 Microchip Technology Inc. dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 2.5 ICSP Pins 2.6 The PGECx and PGEDx pins are used for ICSP 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 respective device Flash programming specification 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) PICkitTM 3, MPLAB ICD 3, or MPLAB REAL ICETM. Many DSCs have options for at least two oscillators: a high-frequency primary oscillator and a low-frequency secondary oscillator. For details, see 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.

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 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 unused pins and drive the output to logic low.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 2. "CPU" (DS70359) in the "dsPIC33E/PIC24E 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 CPU have a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support for digital signal processing. The CPU has a 24-bit instruction word, with a variable length opcode field. The Program Counter (PC) is 24 bits wide and addresses up to 4M x 24 bits of user program memory space. An instruction prefetch mechanism helps maintain throughput and provides predictable execution. Most instructions execute in a single-cycle effective execution rate, with the exception of instructions that change the program flow, the double-word move (MOV.D) instruction, PSV accesses, and the table instructions. Overhead free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any point. 3.1 Registers The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices have sixteen 16-bit Working registers in the programmer's model. Each of the Working registers can act as a data, address or address offset register. The 16th Working register (W15) operates as a software Stack Pointer for interrupts and calls. 3.2 Instruction Set The dsPIC33EPXXXMU806/810/814 instruction set has two classes of instructions: the MCU class of instructions and the DSP class of instructions. The PIC24EPXXXGU810/814 instruction set has the MCU class of instructions and does not support DSP instructions. These two instruction classes are seamlessly integrated into the architecture and execute from a single execution unit. The instruction set includes many addressing modes and was designed for optimum C compiler efficiency. (c) 2009-2011 Microchip Technology Inc. Data Space Addressing The base data space can be addressed as 32K words or 64 Kbytes and is split into two blocks, referred to as X and Y data memory. Each memory block has its own independent Address Generation Unit (AGU). The MCU class of instructions operate solely through the X memory AGU, which accesses the entire memory map as one linear data space. On dsPIC33EPXXXMU806/ 810/814 devices, certain DSP instructions operate through the X and Y AGUs to support dual operand reads, which splits the data address space into two parts. The X and Y data space boundary is device specific. The upper 32 Kbytes of the data space memory map can optionally be mapped into program space at any 16K program word boundary. The program-to-dataspace mapping feature, known as Program Space Visibility (PSV), lets any instruction access program space as if it were data space. Moreover, the Base Data Space address is used in conjunction with a read or write page register (DSRPAG or DSWPAG) to form an Extended Data Space (EDS) address. The EDS can be addressed as 8 Mwords or 16 Mbytes. Refer to Section 3. "Data Memory" (DS70595) and Section 4. "Program Memory" (DS70613) in the "dsPIC33E/ PIC24E Family Reference Manual" for more details on EDS, PSV and table accesses. On dsPIC33EPXXXMU806/810/814 devices, overhead-free circular buffers (Modulo Addressing) are supported in both X and Y address spaces. The Modulo Addressing removes the software boundarychecking overhead for DSP algorithms. The X AGU circular addressing can be used with any of the MCU class of instructions. The X AGU also supports BitReverse Addressing to greatly simplify input or output data reordering for radix-2 FFT algorithms. PIC24EPXXXGU810/814 devices do not support Modulo and Bit-Reverse Addressing. 3.4 Addressing Modes The CPU supports these addressing modes: * * * * * * Inherent (no operand) Relative Literal Memory Direct Register Direct Register Indirect Each instruction is associated with a predefined Addressing mode group, depending upon its functional requirements. As many as six Addressing modes are supported for each instruction.

The IPL<2:0> Status bits are read only when NSTDIS = 1 (INTCON1<15>). A data write to the SR register can modify the SA and SB bits by either a data write to SA and SB or by clearing the SAB bit. To avoid a possible SA or SB bit write race condition, the SA and SB bits should not be modified using bit operations.

Unless otherwise mentioned, arithmetic operations are two's complement in nature. Depending on the operation, the ALU can 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 core CPU incorporates hardware support for both multiplication and division. This includes a dedicated hardware multiplier and support hardware for 16-bit divisor division. 3.7.1 MULTIPLIER Using the high-speed 17-bit x 17-bit multiplier, the ALU supports unsigned, signed, or mixed-sign operation in several MCU multiplication modes: * * * * * * * 16-bit x 16-bit signed 16-bit x 16-bit unsigned 16-bit signed x 5-bit (literal) unsigned 16-bit signed 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 3.7.2 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: 1. 2. 3. 4. DSP Engine (dsPIC33EPXXXMU806/810/814 Devices Only) The DSP engine consists of a high-speed 17-bit x 17-bit multiplier, a 40-bit barrel shifter and a 40-bit adder/subtracter (with two target accumulators, round and saturation logic). The DSP engine can also perform inherent accumulator-to-accumulator operations that require no additional data. These instructions are ADD, SUB and NEG. The DSP engine has options selected through bits in the CPU Core Control register (CORCON), as listed below: * * * * * * Fractional or integer DSP multiply (IF) Signed, unsigned, or mixed-sign DSP multiply (US) Conventional or convergent rounding (RND) Automatic saturation on/off for ACCA (SATA) Automatic saturation on/off for ACCB (SATB) Automatic saturation on/off for writes to data memory (SATDW) * Accumulator Saturation mode selection (ACCSAT) TABLE 3-2: Instruction DSP INSTRUCTIONS SUMMARY Algebraic Operation CLR A=0 ED EDAC MAC MAC MOVSAC MPY MPY MPY.N MSC A = (x - y)2 A = A + (x - y)2 A = A + (x * y) A = A + x2 No change in A A=x*y A = x2 A=-x*y A=A-x*y ACC Write Back Yes No No Yes No Yes No No No Yes 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. 16-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. (c) 2009-2011 Microchip Technology Inc.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 4. "Program Memory" (DS70613) of the "dsPIC33E/PIC24E Family Reference Manual", which is available from the Microchip web site (www.microchip.com). Note: The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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: Program Address Space The program address memory space of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices is 4M instructions. The space is addressable by a 24-bit value derived either from the 23-bit PC during program execution, or from table operation or data space remapping as described in Section 4.6 "Interfacing Program and Data Memory Spaces". User application 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. The memory map for the dsPIC33EPXXXMU806/810/ 814 and PIC24EPXXXGU810/814 devices is shown in Figure 4-1.

Preliminary DS70616C-page 41 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 4.1.1 PROGRAM MEMORY ORGANIZATION 4.1.2 INTERRUPT AND TRAP VECTORS All dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices reserve the addresses between 0x00000 and 0x000200 for hardcoded program execution vectors. 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 application at address 0x000000 of the primary Flash memory or at address 0x7FC000 of the auxiliary Flash memory, with the actual address for the start of code at address 0x000002 of the primary Flash memory or at address 0x7FC002 of the auxiliary Flash memory. Reset Target Vector Select bit (RSTPRI) in the FPOR Configuration register controls whether primary or auxiliary Flash Reset location is used. 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). Program memory addresses are always word-aligned on the lower word, and addresses are incremented or decremented by two during code execution. This arrangement provides compatibility with data memory space addressing and makes data in the program memory space accessible. A more detailed discussion of the interrupt vector tables is provided in Section 7.1 "Interrupt Vector Table".

The data space is accessed using separate Address Generation Units (AGUs) for read and write operations. The data memory maps are shown in Figure 4-3, Figure 4-4, Figure 4-5 and Figure 4-6. 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 base data space address range of 64 Kbytes or 32K words. The base data space address is used in conjunction with a read or write page register (DSRPAG or DSWPAG) to form an extended data space, which has a total address range of 16 MBytes. dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices implement up to 56 Kbytes of data memory. If an EA point to a location outside of this area, an all-zero word or byte is 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 (LSBs) of each word have even addresses, while the Most Significant Bytes (MSBs) 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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++] results in a value of Ws + 1 for byte operations and Ws + 2 for word operations. A data byte read, reads the complete word that contains the byte, using the LSB of any EA to determine which byte to select. The selected byte is placed onto the 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 that matches the byte address. (c) 2009-2011 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 the error occurred on a write, the instruction is executed but the write does not occur. In either case, a trap is then executed, allowing the system and/or user application to examine the machine state prior to execution of the address Fault. All byte loads into any W register are loaded into the LSB. The MSB is not modified. A Sign-Extend instruction (SE) is provided to allow user applications to translate 8-bit signed data to 16-bit signed values. Alternatively, for 16-bit unsigned data, user applications can clear the MSB of any W register by executing a Zero-Extend (ZE) instruction on the appropriate address. 4.2.3 SFR SPACE The first 4 Kbytes of the Near Data Space, from 0x0000 to 0x0FFF, is primarily occupied by Special Function Registers (SFRs). These are used by the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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'. Note: 4.2.4 The actual set of peripheral features and interrupts varies by the device. 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 through 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.

These data spaces can be considered either separate (for some DSP instructions), or as one unified linear address range (for MCU instructions). The data spaces are accessed using two Address Generation Units (AGUs) and separate data paths. This feature allows certain instructions to concurrently fetch two words from RAM, thereby enabling efficient execution of DSP algorithms such as Finite Impulse Response (FIR) filtering and Fast Fourier Transform (FFT). Each dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 device contains 4 Kbytes of dual ported DMA RAM located at the end of Y data RAM and is part of Y data space. 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 transferred from various peripherals using DMA. The DMA RAM can be accessed by the DMA controller without having to steal cycles from the CPU. The PIC24EPXXXGU810/814 devices do not have a Y data space and a Y AGU. For these devices, the entire data space is treated as X data space. 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. The X data space is used by all instructions and supports all addressing modes. X data space has separate read and write data buses. The X read data bus is the read data path for all instructions that view data space as combined X and Y address space. It is also the X data prefetch path for the dual operand DSP instructions (MAC class). Note 1: DMA RAM can be used for general purpose data storage if the DMA function is not required in an application. The Y data space is used in concert with the X data space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. 2: On PIC24EPXXXGU810/814 devices, DMA RAM is located at the end of X data RAM and is part of X data space. Both the X and Y data spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X data space. Modulo Addressing and Bit-Reversed Addressing are not present in PIC24EPXXXGU810/ 814 devices. All data memory writes, including in DSP instructions, view data space as combined X and Y address space. The boundary between the X and Y data spaces is device-dependent and is not user-programmable. DS70616C-page 48 Preliminary (c) 2009-2011 Microchip Technology Inc. File Name Addr.

TABLE 4-64: dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 4.2.7 PAGED MEMORY SCHEME Construction of the EDS address is shown in Figure 4-1. When DSRPAG<9> = 0 and base address bit EA<15> = 1, DSRPAG<8:0> is concatenated onto EA<14:0> to form the 24-bit EDS read address. Similarly when base address bit EA<15>=1, DSWPAG<8:0> is concatenated onto EA<14:0> to form the 24-bit EDS write address. The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 architecture extends the available data space through a paging scheme, which allows the available data space to be accessed using MOV instructions in a linear fashion for pre- and postmodified effective addresses (EA). The upper half of base data space address is used in conjunction with the data space page registers, the 10-bit read page register (DSRPAG) or the 9-bit write page register (DSWPAG), to form an extended data space (EDS) address or Program Space Visibility (PSV) address. The data space page registers are located in the SFR space. EXAMPLE 4-1: EXTENDED DATA SPACE (EDS) READ ADDRESS GENERATION 16-bit DS EA EA<15> = 0 (DSRPAG = don't care) No EDS access Byte Select EA 0 EA<15> Generate PSV address Y DSRPAG<9> = 1? Select DSRPAG 0 EA 1 N DSRPAG<8:0> 9 bits 15 bits 24-bit EDS EA Byte Select Note: DS read access when DSRPAG = 0x000 will force an Address Error trap.

The paged memory scheme provides access to multiple 32-Kbyte windows in the EDS and PSV memory. The data space page registers DSxPAG, in combination with the upper half of data space address can provide up to 16 Mbytes of additional address space in the EDS and 12 Mbytes (DSRPAG only) of PSV address space. The paged data memory space is shown in Example 4-3. The program space (PS) can be accessed with DSRPAG of 0x200 or greater. Only reads from PS are supported using the DSRPAG. Writes to PS are not supported, so DSWPAG is dedicated to DS, including EDS, only. The data space and EDS can be read from and written to using DSRPAG and DSWPAG, respectively.

This is accomplished by setting the DSRPAG register value to the page from which you want to read, and configuring the DSWPAG register to the page to which it needs to be written. Data can also be moved from different PSV to EDS pages, by configuring the DSRPAG and DSWPAG registers to address PSV and EDS space, respectively. The data can be moved between pages by a single instruction. When an EDS or PSV page overflow or underflow occurs, EA<15> is cleared as a result of the register indirect EA calculation. An overflow or underflow of the EA in the EDS or PSV pages can occur at the page boundaries when: * The initial address, prior to modification, addresses an EDS or PSV page. * The EA calculation uses pre- or post-modified register indirect addressing. However, this does not include register offset addressing. TABLE 4-66: In general, when an overflow is detected, the DSxPAG register is incremented, and the EA<15> bit is set to keep the base address within the EDS or PSV window. When an underflow is detected, the DSxPAG register is decremented, and the EA<15> bit is set to keep the base address within the EDS or PSV window. This creates a linear EDS and PSV address space, but only when using Register Indirect Addressing modes. Exceptions to the operation described above arise when entering and exiting the boundaries of page 0, EDS, and PSV spaces. Table 4-66 lists the effects of overflow and underflow scenarios at different boundaries. In the following cases, when overflow or underflow occurs, the EA<15> bit is set and the DSxPAG is not modified; therefore, the EA will wrap to the beginning of the current page: * Register indirect with register offset addressing * Modulo Addressing * Bit-reversed addressing OVERFLOW AND UNDERFLOW SCENARIOS AT PAGE 0, EDS, and PSV SPACE BOUNDARIES Before O/U, Operation R/W DSxPAG DS EA<15> EDS: Last page DSRPAG = 0x1FF 0 See Note 1 1 PSV: Last lsw page DSRPAG = 0x300 1 PSV: First MSB page DSRPAG = 0x3FF 1 PSV: Last MSB page DSRPAG = 0x3FF 0 See Note 1 O, Write DSWPAG = 0x1FF 1 EDS: Last page DSWPAG = 0x1FF 0 See Note 1 U, Read DSRPAG = 0x001 1 PSV page DSRPAG = 0x001 0 See Note 1 DSRPAG = 0x200 1 PSV: First lsw page DSRPAG = 0x200 0 See Note 1 DSRPAG = 0x300 1 PSV: First MSB page DSRPAG = 0x2FF 1 PSV: Last lsw page O, Read O, Read [++Wn] or [Wn++] O, Read [--Wn] or [Wn--] U, Read U, Read Legend: Note 1: 2: 3: 4: DSxPAG DS EA<15> DSRPAG = 0x1FF 1 DSRPAG = 0x2FF After Page Description Page Description O = Overflow, U = Underflow, R = Read, W = Write The register indirect address now addresses a location in the base data space (0x0000-0x8000).

It is indirectly addressable through the register indirect instructions. It can be regarded as being located in the default EDS page 0 (i.e., EDS address range of 0x000000 to 0x007FFF with the base address bit EA<15> = 0 for this address range). However, page 0 cannot be accessed through upper 32 Kbytes, 0x8000 to 0xFFFF, of base data space in combination with DSRPAG = 0x00 or DSWPAG = 0x00. Consequently, DSRPAG and DSWPAG are initialized to 0x001 at Reset. Note 1: DSxPAG should not be used to access page 0. An EDS access with DSxPAG set to 0x000 will generate an Address Error trap. 2: Clearing DSxPAG in software has no effect. FIGURE 4-7: The remaining pages including both EDS and PSV pages are only accessible using the DSRPAG or DSWPAG registers in combination with the upper 32 Kbytes, 0x8000 to 0xFFFF, of the base address, where base address bit EA<15> = 1. For example, when DSRPAG = 0x01 or DSWPAG = 0x01, accesses to the upper 32 Kbytes, 0x8000 to 0xFFFF, of the data space will map to the EDS address range of 0x008000 to 0x00FFFF. When DSRPAG = 0x02 or DSWPAG = 0x02, accesses to the upper 32 Kbytes of the data space will map to the EDS address range of 0x010000 to 0x017FFF and so on, as shown in the EDS memory map in Figure 4-7.

The user application may raise or lower the priority of the masters to be above that of the CPU by setting the appropriate bits in the EDS Bus Master Priority Control (MSTRPR) register. All bus masters with raised priorities will maintain the same priority relationship relative to each other (i.e., M1 being highest and M3 being lowest with M2 in between). Also, all the bus masters with priorities below that of the CPU maintain the same priority relationship relative to each other. The priority schemes for bus masters with different MSTRPR values are tabulated in Table 4-67. EDS accesses from bus masters in the system are arbitrated. The arbiter for data memory (including EDS) arbitrates between the CPU, the DMA, the USB module, and the ICD module. In the event of coincidental access to a bus by the bus masters, the arbiter determines which bus master access has the highest priority. The other bus masters are suspended and processed after the access of the bus by the bus master with the highest priority. This bus master priority control allows the user application to manipulate the real-time response of the system, either statically during initialization, or dynamically in response to real-time events. By default, the CPU is bus master 0 (M0) with the highest priority, and the ICD is bus master 4 (M4) with the lowest priority. The remaining bus masters (USB and DMA Controllers) are allocated to M2 and M3, TABLE 4-67: EDS BUS ARBITER PRIORITY MSTRPR<15:0> Bit Setting(1) Priority 0x0000 0x0008 0x0020 0x0028 M0 (highest) CPU USB DMA USB M1 Reserved CPU CPU DMA M2 USB Reserved Reserved CPU M3 DMA DMA USB Reserved M4 (lowest) ICD ICD ICD ICD Note 1: All other values of MSTRPR<15:0> are Reserved.

This simplifies reading, writing and manipulating of the Stack Pointer (for example, creating stack frames). To protect against misaligned stack accesses, W15<0> is fixed to `0' by the hardware. W15 is initialized to 0x1000 during all Resets. This address ensures that the SP points to valid RAM in all dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices and permits stack availability for non-maskable trap exceptions. These can occur before the SP is initialized by the user software. You can reprogram the SP during initialization to any location within data space. The Stack Pointer always points to the first available free word and fills the software stack working from lower toward higher addresses. Figure 4-9 illustrates how it pre-decrements for a stack pop (read) and postincrements for a stack push (writes). When the PC is pushed onto the stack, PC<15:0> is pushed onto the first available stack word, then PC<22:16> is pushed into the second available stack location. For a PC push during any CALL instruction, the MSB of the PC is zero-extended before the push, as shown in Figure 4-9. During exception processing, the MSB of the PC is concatenated with the lower 8 bits of the CPU STATUS register, SR. This allows the contents of SRL to be preserved automatically during interrupt processing. Note 1: To main system Stack Pointer (W15) coherency, W15 is never subject to (EDS) paging, and is therefore restricted to the address range of 0x0000 to 0xFFFF. The same applies to W14 when used as a Stack Frame Pointer (SFA = 1). 2: As the stack can be placed in and across X, Y, and DMA RAM spaces, care must be exercised regarding its use, particularly with regard to local automatic variables in a C development environment. 4.3 0 PC<15:1> SUBR W15 (before CALL) b`000000000'PC<22:16> <Free Word> W15 (after CALL) Instruction Addressing Modes The addressing modes shown in Table 4-68 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 differ 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 three-operand MCU instructions are of the form: Operand 3 = Operand 1 <function> Operand 2 where Operand 1 is always a working register (that is, 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: * * * * * Register Direct Register Indirect Register Indirect Post-Modified Register Indirect Pre-Modified 5-bit or 10-bit Literal Note: DS70616C-page 116 15 CALL Stack Grows Toward Higher Address Note: 0x0000 CALL STACK FRAME Preliminary Not all instructions support all the addressing modes given above. Individual instructions can support different subsets of these addressing modes.

Register Direct The contents of a register are accessed directly. Register Indirect The contents of Wn forms the Effective Address (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 Indexed) Register Indirect with Literal Offset 4.3.3 The sum of Wn and a literal forms the EA. 4.3.4 MOVE AND ACCUMULATOR INSTRUCTIONS Move instructions (dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814) and the DSP accumulator class of instructions (dsPIC33EPXXXMU806/810/ 814 only) provide a greater degree of addressing flexibility than other instructions. In addition to the addressing modes supported by most MCU instructions, move and accumulator 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 by both source and destination (but typically only used by one). The dual source operand DSP instructions (CLR, ED, EDAC, MAC, MPY, MPY.N, MOVSAC and MSC), also referred to as MAC instructions, use a simplified set of addressing modes to allow the user application to effectively manipulate the data pointers through register indirect tables. The two-source operand prefetch registers must be members of the set {W8, W9, W10, W11}. For data reads, W8 and W9 are always directed to the X RAGU, and W10 and W11 are always directed to the Y AGU. The effective addresses generated (before and after modification) must, therefore, be valid addresses within X data space for W8 and W9 and Y data space for W10 and W11. Note: In summary, the following addressing modes are supported by move and accumulator 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: Register Indirect with Register Offset Addressing mode is available only for W9 (in X space) and W11 (in Y space). In summary, the following addressing modes are supported by the MAC class of instructions: * * * * * Not all instructions support all the addressing modes given above. Individual instructions may support different subsets of these addressing modes. (c) 2009-2011 Microchip Technology Inc.

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, such as ULNK, the source of an operand or result is implied by the opcode itself. Certain operations, such as NOP, do not have any operands. Preliminary DS70616C-page 117 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 4.4 4.4.1 Modulo Addressing (dsPIC33EPXXXMU806/810/814 Devices Only) Modulo Addressing mode is a method of providing an automated means to support circular data buffers using hardware. The objective is to remove the need for software to perform data address boundary checks when executing tightly looped code, as is typical in many DSP algorithms. Modulo Addressing can operate in either data or program space (since the data pointer mechanism is essentially the same for both). One circular buffer can be supported in each of the X (which also provides the pointers into program space) and Y data spaces. Modulo Addressing can operate on any W register pointer. However, it is not advisable to use W14 or W15 for Modulo Addressing since these two registers are used as the Stack Frame Pointer and Stack Pointer, respectively. In general, any particular circular buffer can be configured to operate in only one direction as there are certain restrictions on the buffer start address (for incrementing buffers), or end address (for decrementing buffers), based upon the direction of the buffer. The only exception to the usage restrictions is for buffers that have a power-of-two length. As these buffers satisfy the start and end address criteria, they can operate in a bidirectional mode (that is, address boundary checks are performed on both the lower and upper address boundaries). START AND END ADDRESS The Modulo Addressing scheme requires that a starting and ending address be specified and loaded into the 16-bit Modulo Buffer Address registers: XMODSRT, XMODEND, YMODSRT and YMODEND (see Table 4-1). Note: Y space Modulo Addressing EA calculations assume word-sized data (LSb of every EA is always clear). The length of a circular buffer is not directly specified. It is determined by the difference between the corresponding start and end addresses. The maximum possible length of the circular buffer is 32K words (64 Kbytes). 4.4.2 W ADDRESS REGISTER SELECTION The Modulo and Bit-Reversed Addressing Control register, MODCON<15:0>, contains enable flags as well as a W register field to specify the W Address registers. The XWM and YWM fields select the registers that operate with Modulo Addressing: * If XWM = 15, X RAGU and X WAGU Modulo Addressing is disabled. * If YWM = 15, Y AGU Modulo Addressing is disabled. The X Address Space Pointer W register (XWM), to which Modulo Addressing is to be applied, is stored in MODCON<3:0> (see Table 4-1). Modulo Addressing is enabled for X data space when XWM is set to any value other than `15' and the XMODEN bit is set at MODCON<15>. The Y Address Space Pointer W register (YWM) to which Modulo Addressing is to be applied is stored in MODCON<7:4>. Modulo Addressing is enabled for Y data space when YWM is set to any value other than `15' and the YMODEN bit is set at MODCON<14>.

Address boundaries check for addresses equal to: * The upper boundary addresses for incrementing buffers * The lower boundary addresses for decrementing buffers It is important to realize that the address boundaries check for addresses less than or greater than the upper (for incrementing buffers) and lower (for decrementing buffers) boundary addresses (not just equal to). Address changes can, therefore, jump beyond boundaries and still be adjusted correctly. Note: 4.5 The modulo corrected effective address is written back to the register only when PreModify or Post-Modify Addressing mode is used to compute the effective address. When an address offset (such as [W7 + W2]) is used, Modulo Address correction is performed but the contents of the register remain unchanged. XB<14:0> is the Bit-Reversed Address modifier, or `pivot point,' which is typically a constant. In the case of an FFT computation, its value is equal to half of the FFT data buffer size. Note: The modifier, which can be a constant value or register contents, is regarded as having its bit order reversed. The address source and destination are kept in normal order. Thus, the only operand requiring reversal is the modifier. All bit-reversed EA calculations assume word-sized data (LSb of every EA is always clear). The XB value is scaled accordingly to generate compatible (byte) addresses. When enabled, Bit-Reversed Addressing is executed only for Register Indirect with Pre-Increment or PostIncrement Addressing and word-sized data writes. It does not function for any other addressing mode or for byte-sized data, and normal addresses are generated instead. When Bit-Reversed Addressing is active, the W Address Pointer is always added to the address modifier (XB), and the offset associated with the Register Indirect Addressing mode is ignored. In addition, as word-sized data is a requirement, the LSb of the EA is ignored (and always clear). Note: Bit-Reversed Addressing (dsPIC33EPXXXMU806/810/814 Devices Only) Bit-Reversed Addressing mode is intended to simplify data reordering for radix-2 FFT algorithms. It is supported by the X AGU for data writes only. 4.5.1 If the length of a bit-reversed buffer is M = 2N bytes, the last `N' bits of the data buffer start address must be zeros. Modulo Addressing and Bit-Reversed Addressing should not be enabled together. If an application attempts to do so, Bit-Reversed Addressing assumes priority when active for the X WAGU and X WAGU, Modulo Addressing is disabled. However, Modulo Addressing continues to function in the X RAGU. If Bit-Reversed Addressing has already been enabled by setting the BREN (XBREV<15>) bit, a write to the XBREV register should not be immediately followed by an indirect read operation using the W register that has been designated as the bit-reversed pointer. BIT-REVERSED ADDRESSING IMPLEMENTATION Bit-Reversed Addressing mode is enabled in any of these situations: * BWM bits (W register selection) in the MODCON register are any value other than `15' (the stack cannot be accessed using Bit-Reversed Addressing) * The BREN bit is set in the XBREV register * The addressing mode used is Register Indirect with Pre-Increment or Post-Increment (c) 2009-2011 Microchip Technology Inc.

This capability makes the method ideal for accessing data tables that need to be updated periodically. 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. The application can only access the least significant word of the program word. Interfacing Program and Data Memory Spaces The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 architecture uses a 24-bitwide 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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 4-70: PROGRAM SPACE ADDRESS CONSTRUCTION Access Space Access Type Program Space Address <23> <22:16> <15> <14:1> Instruction Access (Code Execution) User TBLRD/TBLWT (Byte/Word Read/Write) User TBLPAG<7:0> Configuration TBLPAG<7:0> Data EA<15:0> 1xxx xxxx xxxx xxxx xxxx xxxx FIGURE 4-12: PC<22:1> 0 0xx xxxx xxxx 0xxx xxxx <0> 0 xxxx xxxx xxx0 Data EA<15:0> xxxx xxxx xxxx xxxx DATA ACCESS FROM PROGRAM SPACE ADDRESS GENERATION Program Counter(1) Program Counter 0 0 23 bits EA Table Operations(2) 1/0 1/0 TBLPAG 8 bits 16 bits 24 bits User/Configuration Space Select Byte Select Note 1: The Least Significant bit (LSb) of program space addresses is always fixed as `0' to maintain word alignment of data in the program and data spaces. 2: Table operations are not required to be word aligned.

Preliminary DS70616C-page 121 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 4.6.1 DATA ACCESS FROM PROGRAM MEMORY USING TABLE INSTRUCTIONS 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-bitwide word address spaces, residing side by side, each with the same address range. TBLRDL and TBLWTL access the space that contains the least significant data word. TBLRDH and TBLWTH access the space that 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. * TBLRDL (Table Read Low): - In Word mode, this instruction maps the lower word of the program space location (P<15:0>) to a data address (D<15:0>). FIGURE 4-13: - 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'. * TBLRDH (Table Read High): - In Word mode, this instruction maps the entire upper word of a program address (P<23:16>) to a data address. The `phantom' byte (D<15:8>), is always `0'. - In Byte mode, this instruction maps the upper or lower byte of the program word to D<7:0> of the data address, in the TBLRDL instruction. The data is always `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 application 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.

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. FLASH PROGRAM MEMORY Note 1: This data sheet summarizes the features of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 5. "Flash Programming" (DS70609) of the "dsPIC33E/ PIC24E 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 application can write program memory data either in blocks or `rows' of 128 instructions (384 bytes) at a time or a single program memory word, and erase program memory in blocks or `pages' of 1024 instructions (3072 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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: * In-Circuit Serial ProgrammingTM (ICSPTM) programming capability * Run-Time Self-Programming (RTSP) ICSP allows a dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 device to be serially programmed while in the end application circuit. This is done with two lines for programming clock and programming data (one of the alternate programming 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 application to erase a page of memory, which consists of eight rows (1024 instructions) at a time, and to program one row or one word at a time. Table 32-12 lists 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 3072 bytes and 384 bytes, respectively. The program memory implements holding buffers, which are located in the write latch area, that can contain 128 instructions of programming data. Prior to the actual programming operation, the write data must be loaded into the buffers sequentially. 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 128 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. For more information on erasing and programming Flash memory, refer to Section 5. "Flash Programming" (DS70609) in the "dsPIC33E/PIC24E Family Reference Manual". 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 32-19) 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 32-12). PROGRAMMING TIME T --------------------------------------------------------------------------------------------------------------------------7.37 MHz x ( FRC Accuracy )% x ( FRC Tuning )% 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. EQUATION 5-2: MINIMUM ROW WRITE TIME 11064 Cycles T RW = ------------------------------------------------------------------------------------------------ = 1.435ms 7.37 MHz x ( 1 + 0.05 ) x ( 1 - 0.00375 ) The maximum row write time is equal to Equation 5-3. EQUATION 5-3: MAXIMUM ROW WRITE TIME 11064 Cycles T RW = ------------------------------------------------------------------------------------------------ = 1.586ms 7.37 MHz x ( 1 - 0.05 ) x ( 1 - 0.00375 ) Setting the WR bit (NVMCON<15>) starts the operation, and the WR bit is automatically cleared when the operation is finished. 5.4 Control Registers Four SFRs are used to read and write the program Flash memory: NVMCON, NVMKEY, NVMADRU, and NVMADR. The NVMCON register (Register 5-1) controls which blocks are to be erased, which memory type is to be programmed and the start of the programming cycle. NVMKEY (Register 5-4) is a write-only register that is used for write protection. To start a programming or erase sequence, the user application must consecutively write 0x55 and 0xAA to the NVMKEY register. There are two NVM address registers: NVMADRU and NVMADR. These two registers, when concatenated, form the 24-bit effective address (EA) of the selected row or word for programming operations, or the selected page for erase operations. The NVMADRU register is used to hold the upper 8 bits of the EA, while the NVMADR register is used to hold the lower 16 bits of the EA.

Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The Reset module combines all reset sources and controls the device Master Reset Signal, SYSRST. The following is a list of device Reset sources: * * * * * * * * POR: Power-on Reset BOR: Brown-out Reset MCLR: Master Clear Pin Reset SWR: RESET Instruction WDTO: Watchdog Timer Reset CM: Configuration Mismatch Reset TRAPR: Trap Conflict Reset IOPUWR: Illegal Condition Device Reset - Illegal Opcode Reset - Uninitialized W Register Reset - Security Reset FIGURE 6-1: Any active source of Reset will make the SYSRST signal active. On system Reset, some of the registers associated with the CPU and peripherals are forced to a known Reset state and some are unaffected. Note: Refer to the specific peripheral section or Section 4.0 "Memory Organization" of this manual for register Reset states. All types of device Reset sets a corresponding status bit in the RCON register to indicate the type of Reset (see Register 6-1). A POR clears all the bits, except for the POR and BOR bits (RCON<1:0>), that are set. The user application 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 is meaningful.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 6.

Refer to Section 4.0 "Memory Organization" in this data sheet for device-specific register and bit information. The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 interrupt controller reduces the numerous peripheral interrupt request signals to a single interrupt request signal to the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 CPU. The interrupt controller has the following features: * Up to eight processor exceptions and software traps * Eight user-selectable priority levels * Interrupt Vector Table (IVT) with a unique vector for each interrupt or exception source * Fixed priority within a specified user priority level * Fixed interrupt entry and return latencies (c) 2009-2011 Microchip Technology Inc. Interrupt Vector Table The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 Interrupt Vector Table (IVT), shown in Figure 7-1, resides in program memory, starting at location 000004h. The IVT contains seven non-maskable trap vectors and up to 114 sources of interrupt. In general, each interrupt source has its own vector. Each interrupt vector contains a 24bit-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. Lower addresses generally have a higher natural priority. For example, the interrupt associated with vector 0 takes priority over interrupts at any other vector address. 7.2 Reset Sequence A device Reset is not a true exception because the interrupt controller is not involved in the Reset process. The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices clear their registers in response to a Reset, which forces the PC to zero. The digital signal controller then begins program execution at location 0x000000. A GOTO instruction at the Reset address can redirect program execution to the appropriate start-up routine. Note: Preliminary Any unimplemented or unused vector locations in the IVT should be programmed with the address of a default interrupt handler routine that contains a RESET instruction.

Preliminary DS70616C-page 135 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 7.3 7.3.4 Interrupt Control and Status Registers dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices implement the following registers for the interrupt controller: * * * * * INTCON1 INTCON2 INTCON3 INTCON4 INTTREG 7.3.1 Global interrupt control functions are controlled from INTCON1, INTCON2, INTCON3 and INTCON4. INTCON1 contains the Interrupt Nesting Disable bit (NSTDIS) as well as the control and status flags for the processor trap sources. The INTCON2 register controls external interrupt request signal behavior and the use of the alternate vector table. This register also contains the General Interrupt Enable bit (GIE). INTCON3 contains the status flags for the USB, DMA, and DO stack overflow status trap sources. 7.3.2 software IFSx 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. 7.3.3 IECx 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. DS70616C-page 136 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. 7.3.5 INTTREG The INTTREG register contains the associated interrupt vector number and the new CPU interrupt priority level, which are latched into vector number (VECNUM<7:0>) and Interrupt level bit (ILR<3:0>) fields in the INTTREG register. The new interrupt priority level is the priority of the pending interrupt. INTCON1 THROUGH INTCON4 The INTCON4 register contains the generated hard trap status bit (SGHT). IPCx The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence as 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>). 7.3.6 STATUS/CONTROL REGISTERS Although these registers are not specifically part of the interrupt control hardware, two of the CPU Control registers contain bits that control interrupt functionality. For more information on these registers refer to Section 2. "CPU" (DS70359) in the "dsPIC33E/ PIC24E Family Reference Manual". * 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 software 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 7-3 through Register 7-7 in the following pages.

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)" (DS70348) of the "dsPIC33E/PIC24E 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 DMA controller transfers data between peripheral data registers and data space SRAM. The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 DMA subsystem uses dualported SRAM memory (DPSRAM) and register structures that allow the DMA to operate across its own, independent address and data buses with no impact on CPU operation. This architecture eliminates the need for cycle stealing, which halts the CPU when a higher priority DMA transfer is requested. Both the CPU and DMA controller can write and read to/from FIGURE 8-1: addresses within data space without interference, such as CPU stalls, resulting in maximized, real-time performance. Alternatively, DMA operation and data transfer to/from the memory and peripherals are not impacted by CPU processing. For example, when a Run-Time Self-Programming (RTSP) operation is performed, the CPU does not execute any instructions until RTSP is finished. This condition, however, does not impact data transfer to/from memory and the peripherals. In addition, DMA can access entire data memory space (SRAM and DPSRAM). The Data Memory Bus Arbiter is utilized when either the CPU or DMA attempt to access non-dual-ported SRAM, resulting in potential DMA or CPU stalls. The DMA controller supports up to 15 independent channels. Each channel can be configured for transfers to or from selected peripherals. Some of the peripherals supported by the DMA controller include: * * * * * * * * ECANTM Data Converter Interface (DCI) Analog-to-Digital Converter (ADC) Serial Peripheral Interface (SPI) UART Input Capture Output Compare Parallel Master Port (PMP) Refer to Table 8-1 for a complete list of supported peripherals.

Preliminary DS70616C-page 145 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 In addition, DMA transfers can be triggered by Timers as well as external interrupts. Each DMA channel is unidirectional. Two DMA channels must be allocated to read and write to a peripheral. If more than one channel receive a request to transfer data, a simple fixed priority scheme, based on channel number, dictates which channel completes the transfer and which channel, or channels, are left pending. Each DMA channel moves a block of data, after which it generates an interrupt to the CPU to indicate that the block is available for processing. The DMA controller capabilities: provides these functional * Up to 15 DMA channels * Register Indirect With Post-increment Addressing mode * Register Indirect Without Post-increment Addressing mode TABLE 8-1: * Peripheral Indirect Addressing mode (peripheral generates destination address) * CPU interrupt after half or full-block transfer complete * Byte or word transfers * Fixed priority channel arbitration * Manual (software) or Automatic (peripheral DMA requests) transfer initiation * One-Shot or Auto-Repeat block transfer modes * Ping-Pong mode (automatic switch between two DPSRAM start addresses after each block transfer complete) * DMA request for each channel can be selected from any supported interrupt source Debug support features The peripherals that can utilize DMA are listed in Table 8-1.

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" (DS70615) of the "dsPIC33E/PIC24E 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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. Instruction-Based Power-Saving Modes The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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 assembler 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 The following occur in Sleep mode: 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. * 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, 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 can continue to operate. 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. 10.1 The device wakes up from Sleep mode on any of the these events: dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices can manage power consumption in four ways: * * * * Clock frequency Instruction-based Sleep and Idle modes Software-controlled Doze mode Selective peripheral control in software Clock Frequency and Clock Switching The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 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: * Any interrupt source that is individually enabled * Any form of device Reset * A WDT time-out On wake-up from Sleep mode, 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 (c) 2009-2011 Microchip Technology Inc. Preliminary DS70616C-page 173 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 10.2.2 IDLE MODE The following occur in Idle mode: * 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 wakes 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 mode, 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 The preferred strategies for reducing power consumption are changing clock speed and invoking one of the power-saving modes. In some circumstances, this cannot be 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 can introduce communication errors, while using a power-saving mode can stop communications completely. 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. Programs can 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. An automatic return to full-speed CPU operation on interrupts can be 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 ECAN module has been configured for 500 kbps based on this device operating speed. If the device is placed in Doze mode with a clock frequency ratio of 1:4, the ECAN 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 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 using 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 do not have effect and read values are invalid. A peripheral module is enabled only 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: 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. DS70616C-page 174 Peripheral Module Disable Preliminary If a PMD bit is set, the corresponding module is disabled after a delay of one instruction cycle. Similarly, if a PMD bit is cleared, the corresponding module is enabled after a delay of one instruction cycle (assuming the module control registers are already configured to enable module operation).

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" (DS70598) of the "dsPIC33E/PIC24E 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/CLKI) are shared among 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 Generally, a parallel I/O port that shares a pin with a peripheral is 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 FIGURE 11-1: the I/O pin. The logic also prevents "loop through," in which a port's digital output can drive the input of a peripheral that shares the same pin. Figure 11-1 illustrates how ports are shared with other peripherals and the associated I/O pin to which they are connected. When a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The I/O pin can be read, but the output driver for the parallel port bit is disabled. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin can be driven by a port. All port pins have eight 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', then the pin is 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 is disabled. This means the corresponding LATx and TRISx registers and the port pin are read as zeros. When a pin is shared with another peripheral or function that is defined as an input only, it is nevertheless regarded as a dedicated port because there is no other competing source of outputs.

Preliminary DS70616C-page 187 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 11.1.1 OPEN-DRAIN CONFIGURATION 11.3 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 a 5V tolerant pin) by using external pull-up resistors. The maximum open-drain voltage allowed is the same as the maximum VIH specification for that pin. See the "Pin Diagrams" section for the available pins and their functionality. 11.2 Configuring Analog and Digital Port Pins The ANSELx register controls the operation of the analog port pins. The port pins that are to function as analog inputs must have their corresponding ANSEL and TRIS bits set. In order to use port pins for I/O functionality with digital modules, such as Timers, UARTs, etc., the corresponding ANSELx bit must be cleared. The ANSELx register has a default value of 0xFFFF; therefore, all pins that share analog functions are analog (not digital) by default. If the TRIS bit is cleared (output) while the ANSELx bit is set, the digital output level (VOH or VOL) is converted by an analog peripheral, such as the ADC module or Comparator module. When the PORT register is read, all pins configured as analog input channels are read as cleared (a low level). Pins configured as digital inputs do not convert an analog input. Analog levels on any pin defined as a digital input (including the ANx pins) can cause the input buffer to consume current that exceeds the device specifications. 11.2.1 Input Change Notification The input change notification function of the I/O ports allows the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices to generate interrupt requests to the processor in response to a change-ofstate on selected input pins. This feature can detect input change-of-states even in Sleep mode, when the clocks are disabled. Every I/O port pin can be selected (enabled) for generating an interrupt request on a change-of-state. Three control registers are associated with the CN functionality of each I/O port. The CNENx registers contain the CN interrupt enable control bits for each of the input pins. Setting any of these bits enables a CN interrupt for the corresponding pins. Each I/O pin also has a weak pull-up and a weak pull-down connected to it. The pull-ups act as a current source or sink source connected to the pin, and eliminate the need for external resistors when push-button or keypad devices are connected. The pull-ups and pull-downs are enabled separately using the CNPUx and the CNPDx registers, which contain the control bits for each of the pins. Setting any of the control bits enables the weak pull-ups and/or pull-downs for the corresponding pins. Note: Pull-ups and pull-downs on change notification pins should always be disabled when the port pin is configured as a digital output.

Typically this instruction would be an NOP, as shown in Example 11-1. DS70616C-page 188 Preliminary (c) 2009-2011 Microchip Technology Inc. dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 11.4 Peripheral Pin Select A major challenge in general purpose devices is providing the largest possible set of peripheral features while minimizing the conflict of features on I/O pins. The challenge is even greater on low pin-count devices. In an application where more than one peripheral needs to be assigned to a single pin, inconvenient workarounds in application code or a complete redesign may be the only option. Peripheral pin select configuration provides an alternative to these choices by enabling peripheral set selection and their placement on a wide range of I/O pins. By increasing the pinout options available on a particular device, users can better tailor the device to their entire application, rather than trimming the application to fit the device. The peripheral pin select configuration feature operates over a fixed subset of digital I/O pins. Users may independently map the input and/or output of most digital peripherals to any one of these I/O pins. Peripheral pin select is performed in software and generally does not require the device to be reprogrammed. Hardware safeguards are included that prevent accidental or spurious changes to the peripheral mapping once it has been established. 11.4.1 AVAILABLE PINS The number of available pins is dependent on the particular device and its pin count. Pins that support the peripheral pin select feature include the designation "RPn" or "RPIn" in their full pin designation, where "RP" designates a remappable function for input or output and "RPI" designates a remappable functions for input only, and "n" is the remappable pin number. 11.4.2 AVAILABLE PERIPHERALS The peripherals managed by the peripheral pin select are all digital-only peripherals. These include general serial communications (UART and SPI), general purpose timer clock inputs, timer-related peripherals (input capture and output compare) and interrupt-on-change inputs. In comparison, some digital-only peripheral modules are never included in the peripheral pin select feature. This is because the peripheral's function requires special I/O circuitry on a specific port and cannot be easily connected to multiple pins. These modules include I2C and the PWM. A similar requirement excludes all modules with analog inputs, such as the A/D converter. A key difference between remappable and non-remappable peripherals is that remappable peripherals are not associated with a default I/O pin. The peripheral must always be assigned to a specific I/O pin before it can be used. In contrast, non-remappable peripherals are always available on a default pin, assuming that the peripheral is active and not conflicting with another peripheral. (c) 2009-2011 Microchip Technology Inc. When a remappable peripheral is active on a given I/O pin, it takes priority over all other digital I/O and digital communication peripherals associated with the pin. Priority is given regardless of the type of peripheral that is mapped. Remappable peripherals never take priority over any analog functions associated with the pin. 11.4.3 CONTROLLING PERIPHERAL PIN SELECT Peripheral pin select features are controlled through two sets of SFRs: one to map peripheral inputs, and one to map outputs. Because they are separately controlled, a particular peripheral's input and output (if the peripheral has both) can be placed on any selectable function pin without constraint. The association of a peripheral to a peripheral-selectable pin is handled in two different ways, depending on whether an input or output is being mapped. 11.4.3.1 INPUT MAPPING The inputs of the peripheral pin select options are mapped on the basis of the peripheral. That is, a control register associated with a peripheral dictates the pin it will be mapped to. The RPINRx registers are used to configure peripheral input mapping (see Register 11-1 through Register 11-22). Each register contains sets of 7-bit fields, with each set associated with one of the remappable peripherals (see Table 11-1). Programming a given peripheral's bit field with an appropriate 7-bit value maps the RPn/RPIn pin with the corresponding value to that peripheral (see Table 11-2). For any given device, the valid range of values for any bit field corresponds to the maximum number of peripheral pin selections supported by the device. For example, Figure 11-2 illustrates remappable pin selection for the U1RX input.

In this case, a control register associated with a particular pin dictates the peripheral output to be mapped. The RPORx registers are used to control output mapping. Like the RPINRx registers, each register contains sets of 6 bit fields, with each set associated with one RPn pin (see Register 11-44 through Register 11-51). The value of the bit field corresponds to one of the peripherals, and that peripheral's output is mapped to the pin (see Table 11-3 and Figure 11-3). A null output is associated with the output register reset value of `0'. This is done to ensure that remappable outputs remain disconnected from all output pins by default.

Preliminary DS70616C-page 195 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 11.4.3.3 Virtual Connections The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices support virtual (internal) connections to the output of the comparator modules CMP1OUT, CMP2OUT and CMP3OUT (see Figure 25-1 in Section 25.0 "Comparator Module"). In addition, dsPIC33EPXXXMU806/810/814 devices support virtual connections to the filtered QEI module inputs FINDX1, FHOME1, FINDX2 and FHOME2 (see Figure 17-1 in Section 17.0 "Quadrature Encoder Interface (QEI) Module (dsPIC33EPXXXMU806/810/ 814 Devices Only)". Virtual connections provide a simple way of interperipheral connection without utilizing a physical pin. For example, by setting the FLT1R<6:0> bits of the RPINR12 register to the value of `b0000001, the output of the Analog Comparator CMP1OUT will be connected to the PWM Fault 1 input, which allows the Analog Comparator to trigger PWM faults without the use of an actual physical pin on the device. EXAMPLE 11-1: Virtual connection to the QEI module allows peripherals to be connected to the QEI digital filter input. To utilize this filter, the QEI module must be enabled, and its inputs must be connected to a physical RPn/RPIn pin. Example 11-1 illustrates how the input capture module can be connected to the QEI digital filter. 11.4.3.4 Mapping Limitations The control schema of the peripheral select pins is not limited to a small range of fixed peripheral configurations. There are no mutual or hardwareenforced lockouts between any of the peripheral mapping SFRs. Literally any combination of peripheral mappings across any or all of the RPn/RPIn pins is possible. This includes both many-to-one and one-tomany mappings of peripheral inputs and outputs to pins. While such mappings may be technically possible from a configuration point of view, they may not be supportable from an electrical point of view.

A block diagram of Timer1 is shown in Figure 12-1. TIMER1 Note 1: This data sheet summarizes the features of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 11. "Timers" (DS70362) of the "dsPIC33E/PIC24E Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The Timer1 module can operate in one of the following modes: * * * * In Timer and Gated Timer modes, the input clock is derived from the internal instruction cycle clock (FCY). In Synchronous and Asynchronous Counter modes, the input clock is derived from the external clock input at the T1CK pin. 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 Timer modes are determined by the following bits: * Timer Clock Source Control bit (TCS): T1CON<1> * Timer Synchronization Control bit (TSYNC): T1CON<2> * Timer Gate Control bit (TGATE): T1CON<6> The Timer1 module is a 16-bit timer, which can serve as the time counter for the real-time clock, or operate as a free-running interval timer/counter. Timer control bit setting for different operating modes are given in the Table 12-1. The Timer1 module has the following unique features over other timers: * Can be operated from the low-power 32 kHz crystal oscillator available on the device. * Can be operated in Asynchronous Counter mode from an external clock source. * The external clock input (T1CK) can optionally be synchronized to the internal device clock and the clock synchronization is performed after the prescaler.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 11. "Timers" (DS70362) of the "dsPIC33E/PIC24E 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. 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: 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 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. A block diagram for a 32-bit timer pair (Timer4/5) example is shown in Figure 13-1 and a timer (Timer4) operating in 16-bit mode example is shown in Figure 13-2. Note: Only Timer2, 3, 4 and 5 can trigger a DMA data transfer. 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) (c) 2009-2011 Microchip Technology Inc.

The module compares the value of the timer with the value of one or two compare registers depending on the operating mode selected. The state of the output pin changes when the timer value matches the compare register value. The output compare module generates either a single output pulse or a sequence of output pulses, by changing the state of the output pin on the compare match events. The output compare module can also generate interrupts on compare match events.

The High-Speed PWM module consists of the following major features: * Two master time base modules with special event triggers * PWM module input clock prescaler * Two synchronization inputs * Two synchronization outputs * Up to seven PWM generators * Two PWM outputs per generator (PWMxH and PWMxL) * Individual period, duty cycle and phase shift for each PWM output * Period, duty cycle, phase shift and dead-time resolution of 8.32 ns * Immediate update mode for PWM period, duty cycle and phase shift * Independent fault and current-limit inputs for each PWM * Cycle by cycle and latched fault modes * PWM time-base capture upon current limit * Seven fault inputs and three comparator outputs available for faults and current-limits * Programmable A/D trigger with interrupt for each PWM pair * Complementary PWM outputs * Push-Pull PWM outputs * Redundant PWM outputs * Edge-Aligned PWM mode * Center-Aligned PWM mode * Variable Phase PWM mode (c) 2009-2011 Microchip Technology Inc. * * * * * * * * * * * Multi-Phase PWM mode Fixed-Off Time PWM mode Current Limit PWM mode Current Reset PWM mode PWMxH and PWMxL output override control PWMxH and PWMxL output pin swapping Chopping mode (also known as Gated mode) Dead-time insertion Dead-time compensation Enhanced Leading-Edge Blanking (LEB) 8 mA PWM pin output drive Note: Duty cycle, dead-time, phase shift and frequency resolution is 16.64 ns in Center-Aligned PWM mode. The High-Speed PWM module contains up to seven PWM generators. Each PWM generator provides two PWM outputs: PWMxH and PWMxL. Two master time base generators provide a synchronous signal as a common time base to synchronize the various PWM outputs. Each generator can operate independently or in synchronization with either of the two master time bases. The individual PWM outputs are available on the output pins of the device. The input Fault signals and current-limit signals, when enabled, can monitor and protect the system by placing the PWM outputs into a known "safe" state. Each PWM can generate a trigger to the ADC module to sample the analog signal at a specific instance during the PWM period. In addition, the High-Speed PWM module also generates two Special Event Triggers to the ADC module based on the two master time bases. The High-Speed PWM module can synchronize itself with an external signal or can act as a synchronizing source to any external device. The SYNCI1 and SYNCI2 pins are the input pins, which can synchronize the High-Speed PWM module with an external signal. The SYNCO1 and SYNCO2 pins are output pins that provides a synchronous signal to an external device. Figure 16-1 illustrates an architectural overview of the High-Speed PWM module and its interconnection with the CPU and other peripherals.

These modules, which are designated as SPI1, SPI2, SPI3 and SPI4, are functionally identical. Each SPI module includes an eight-word FIFO buffer and allows DMA bus connections. When using the SPI module with DMA, FIFO operation can be disabled. SERIAL PERIPHERAL INTERFACE (SPI) Note 1: This data sheet summarizes the features of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 18. "Serial Peripheral Interface (SPI)" (DS70569) of the "dsPIC33E/PIC24E Family Reference Manual", which is available from the Microchip web site (www.microchip.com). Note: 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 SPIx serial interface consists of four pins, as follows: The SPI module is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices can be serial EEPROMs, shift registers, display drivers, A/D converters, etc. The SPI module is compatible with Motorola's SPI and SIOP interfaces. FIGURE 18-1: * * * * SDIx: Serial Data Input SDOx: Serial Data Output SCKx: Shift Clock Input or Output SSx/FSYNCx: Active-Low Slave Select or Frame Synchronization I/O Pulse The SPIx module can be configured to operate with two, three or four pins. In 3-pin mode, SSx is not used. In 2-pin mode, neither SDOx nor SSx is used. Figure 18-1 illustrates the block diagram of the SPI module in Standard and Enhanced modes. SPIx MODULE BLOCK DIAGRAM SCKx SSx/FSYNCx In this section, the SPI modules are referred to together as SPIx, or separately as SPI1, SPI2, SPI3 and SPI4.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 21. "Enhanced Controller Area Network (ECANTM)" (DS70353) of the "dsPIC33E/PIC24E 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. 21.1 Overview The Enhanced Controller Area Network (ECAN) 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices contain two ECAN modules. The ECAN module is a communication controller implementing the CAN 2.0 A/B protocol, as defined in the BOSCH CAN specification. The module supports 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 can refer to the BOSCH CAN specification for further details. (c) 2009-2011 Microchip Technology Inc. * 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 eight transmit buffers with application specified prioritization and abort capability (each buffer can contain up to 8 bytes of data) * Up to 32 receive buffers (each buffer can contain up to 8 bytes of data) * Up to 16 full (standard/extended identifier) acceptance filters * Three full acceptance filter masks * DeviceNetTM addressing support * Programmable wake-up functionality with integrated low-pass filter * Programmable Loopback mode supports self-test operation * Signaling via interrupt capabilities for all CAN receiver and transmitter error states * Programmable clock source * Programmable link to Input Capture module (IC2 for the ECAN1 and ECAN2 modules) for timestamping 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.

These modes include: * * * * * * Initialization mode Disable mode Normal Operation mode Listen Only mode Listen All Messages mode Loopback mode DS70616C-page 328 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 does 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. Refer to Section 21. "Enhanced Controller Area Network (ECANTM)" (DS70353) of the "dsPIC33E/ PIC24E Family Reference Manual" for more details on ECAN.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 25. "USB OnThe-Go (OTG))" (DS70571) of the "dsPIC33E/PIC24E 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. 22.1 Overview The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 Universal Serial Bus (USB) On-The-Go (OTG) module includes the following features: * * * * * * * * * * * * USB full-speed support for host and device Low-speed host support USB On-The-Go support Integrated signaling resistors Integrated analog comparators for VBUS monitoring Integrated USB transceiver Hardware performs transaction handshaking Endpoint buffering anywhere in system RAM Integrated DMA controller to access system RAM Support for all four transfer types: - Control - Interrupt - Bulk data - Isochronous Queueing of up to four endpoint transfers without servicing USB 5V charge pump controller (c) 2009-2011 Microchip Technology Inc. The USB module contains the analog and digital components to provide a USB 2.0 full-speed and lowspeed embedded host, full-speed device, or OTG implementation with a minimum of external components. The USB module consists of the clock generator, the USB voltage comparators, the transceiver, the Serial Interface Engine (SIE), pull-up and pull-down resistors, and the register interface. Figure 22-1 illustrates the block diagram of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 Output Compare module. The device auxiliary clock generator provides the 48 MHz clock required for USB communication. The voltage comparators monitor the voltage on the VBUS pin to determine the state of the bus. The transceiver provides the analog translation between the USB bus and the digital logic. The SIE is a state machine that transfers data to and from the endpoint buffers and generates the protocol for data transfers. The integrated pull-up and pull-down resistors eliminate the need for external signaling components. The register interface allows the CPU to configure and communicate with the module. Note: The implementation and use of the USB specifications and other third party specifications or technology may require a license from various entities, including, but not limited to USB Implementers Forum, Inc. (also referred to as USB-IF). It is your responsibility to obtain more information regarding any applicable licensing obligations. 22.1.1 Clearing USB OTG Interrupts Unlike device level interrupts, the USB OTG interrupt status flags are not freely writable in software. All USB OTG flag bits are implemented as hardware set-only bits. Additionally, these bits can only be cleared in software by writing a `1' to their locations (i.e., performing a BSET instruction). Writing a `0' to a flag bit (i.e., a BCLR instruction) has no effect.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to Section 16. "Analog-toDigital Converter (ADC)" (DS70621) of the "dsPIC33E/PIC24E 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 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices have two ADC modules, ADC1 and ADC2. The ADC1 module supports up to 32 analog input channels. The ADC2 module supports up to 16 analog input channels. On ADC1, the AD12B bit (AD1CON1<10>) allows each of the ADC modules to be configured by the user as either a 10-bit, 4 Sample and Hold (S&H) ADC (default configuration) or a 12-bit, 1 S&H ADC. Note: The ADC1 module needs to be disabled before modifying the AD12B bit. The ADC2 module only supports 10-bit operation with 4 S&H. (c) 2009-2011 Microchip Technology Inc. Key Features The 10-bit ADC configuration has the following key features: * * * * * * * * * * 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 Four result alignment options (signed/unsigned, fractional/integer) 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 one S&H amplifier in the 12-bit configuration, so simultaneous sampling of multiple channels is not supported. Depending on the particular device pinout, the ADC 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 can be shared with other analog input pins. The actual number of analog input pins and external voltage reference input configuration depends on the specific device. A block diagram of the ADC module is shown in Figure 23-1.

FIGURE 25-1: The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 Comparator module provides three comparators that can be configured in different ways. As shown in Figure 25-1, individual comparator options are specified by the Comparator module's Special Function Register (SFR) control bits. These options allow users to: * Select the edge for trigger and interrupt generation * Configure the comparator voltage reference and band gap * Configure output blanking and masking The comparator operating mode is determined by the input selections (i.e., whether the input voltage is compared to a second input voltage, to an internal voltage reference.

"Real-Time Clock and Calendar (RTCC)" (DS70584) of the "dsPIC33E/PIC24E Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The RTCC module is intended for applications where accurate time must be maintained for extended periods with minimum to no intervention from the CPU. The RTCC module is optimized for low-power usage to provide extended battery lifetime while keeping track of 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. This chapter discusses the Real-Time Clock and Calendar (RTCC) module, available on dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices, and its operation. FIGURE 26-1: Time: hours, minutes, and seconds 24-hour format (military time) Calendar: weekday, date, month and year Alarm configurable Year range: 2000 to 2099 Leap year correction BCD format for compact firmware Optimized for low-power operation User calibration with auto-adjust Calibration range: 2.64 seconds error per month Requirements: External 32.768 kHz clock crystal Alarm pulse or seconds clock output on RTCC pin The RTCC module is a 100-year clock and calendar with automatic leap year detection. The range of the clock is from 00:00:00 (midnight) on January 1, 2000 to 23:59:59 on December 31, 2099. The hours are available in 24-hour (military time) format. The clock provides a granularity of one second with half-second visibility to the user.

For further details, refer to Section 7. "Oscillator" (DS70580) in the 'dsPIC33E/PIC24E Family Reference Manual'. The user application can configure the time and calendar by writing the desired seconds, minutes, hours, weekday, date, month, and year to the RTCC registers. Under normal operation, writes to the RTCC timer registers are not allowed. Attempted writes will appear to execute normally, but the contents of the registers will remain unchanged. To write to the RTCC register, the RTCWREN bit (RCFGCAL<13>) must be set. Setting the RTCWREN bit allows writes to the RTCC registers. Conversely, clearing the RTCWREN bit prevents writes. DS70616C-page 410 To set the RTCWREN bit, the following procedure must be executed. The RTCWREN bit can be cleared at any time: 1. 2. 3. Write 0x55 to NVMKEY. Write 0xAA to NVMKEY. Set the RTCWREN bit using a single cycle instruction. The RTCC module is enabled by setting the RTCEN bit (RCFGCAL<15>). To set or clear the RTCEN bit, the RTCWREN bit (RCFGCAL<13>) must be set. If the entire clock (hours, minutes, and seconds) needs to be corrected, it is recommended that the RTCC module should be disabled to avoid coincidental write operation when the timer increment. Therefore, it stops the clock from counting while writing to the RTCC Timer register.

Preliminary DS70616C-page 419 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 27.1 Overview The CRC module can be programmed for CRC polynomials of up to the 32nd order, using up to 32 bits. Polynomial length, which reflects the highest exponent in the equation, is selected by the PLEN<4:0> bits (CRCCON2<4:0>). The CRCXORL and CRCXORH registers control which exponent terms are included in the equation. Setting a particular bit includes that exponent term in the equation; functionally, this includes an XOR operation on the corresponding bit in the CRC engine. Clearing the bit disables the XOR. TABLE 27-1: For example, consider two CRC polynomials, one a 16bit equation and the other a 32-bit equation: x16 + x12 + x5 + 1 and x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1 To program these polynomials into the CRC generator, set the register bits as shown in Table 27-1. Note that the appropriate positions are set to `1' to indicate that they are used in the equation (for example, X26 and X23). The 0 bit required by the equation is always XORed; thus, X0 is a don't care. For a polynomial of length N, it is assumed that the Nth bit will always be used, regardless of the bit setting. Therefore, for a polynomial length of 32, there is no 32nd bit in the CRCxOR register.

Refer to Section 30. "Device Configuration" (DS70618) of the "dsPIC33E/PIC24E Family Reference Manual" for more information on this implementation. This data sheet summarizes the features of the dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section of the "dsPIC33E/PIC24E 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. dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices include several features intended to maximize application flexibility and reliability, and minimize cost through elimination of external components. These are: * * * * * * Configuration Bits The individual Configuration bit descriptions for the Configuration registers are shown in Table 29-2. Note that address 0xF80000 is beyond the user program memory space. It belongs to the configuration memory space (0x800000-0xFFFFFF), which can only be accessed using table reads and table writes. Flexible configuration Watchdog Timer (WDT) Code Protection and CodeGuardTM Security JTAG Boundary Scan Interface In-Circuit Serial ProgrammingTM (ICSPTM) In-Circuit emulation To prevent inadvertent configuration changes during code execution, some programmable Configuration bits are write-once. For such bits, changing a device configuration requires that the device be Reset. For other Configuration bits, the device configuration changes immediately after an RTSP operation. The RTSP Effect column in Table 29-2 indicates when the device configuration changes after a bit is modified using RTSP. The Device Configuration register map is shown in Table 29-1.

This can create a conflict for designs that are required to operate at a higher typical voltage, such as 3.3V. To simplify system design, all devices in the dsPIC33EPXXXMU806/810/ 814 and PIC24EPXXXGU810/814 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. A low-ESR (less than 1 Ohms) capacitor (such as tantalum or ceramic) must be connected to the VCAP pin (Figure 29-1). This helps to maintain the stability of the regulator. The recommended value for the filter capacitor is provided in Table 32-13 located in Section 32.0 "Electrical Characteristics". Note: It is important for the low-ESR capacitor to be placed as close as possible to the VCAP pin. FIGURE 29-1: CONNECTIONS FOR THE ON-CHIP VOLTAGE REGULATOR(1) 3.3V dsPIC33E/PIC24E VCAP VSS A BOR generates a Reset pulse, which resets the device. The BOR selects the clock source, based on the device Configuration bit values (FNOSC<2:0> and POSCMD<1:0>). If an oscillator mode is selected, the BOR activates the Oscillator Start-up Timer (OST). The system clock is held until OST expires. If the PLL is used, the clock is held until the LOCK bit (OSCCON<5>) is `1'. Concurrently, the PWRT time-out (TPWRT) is applied before the internal Reset is released. If TPWRT = 0 and a crystal oscillator is being used, then a nominal delay of TFSCM is applied. The total delay in this case is TFSCM. Refer to parameter SY35 in Table 32-22 of Section 32.0 "Electrical Characteristics" for specific TFSCM values. Note: Note 1: These are typical operating voltages. Refer to Section TABLE 32-13: "Internal Voltage Regulator Specifications" located in Section 32.1 "DC Characteristics" for the full operating ranges of VDD and VCAP. 2: It is important for the low-ESR capacitor to be placed as close as possible to the VCAP pin. (c) 2009-2011 Microchip Technology Inc. The Brown-out Reset module is based on an internal voltage reference circuit that monitors the regulated supply voltage VCAP. The main purpose of the BOR module is to generate a device Reset when a brownout condition occurs. Brown-out conditions are generally caused by glitches on the AC mains (for example, 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). The BOR feature is enabled by setting the BOREN Configuration bit (FPOR<3>). The BOR Status bit (RCON<1>) is set to indicate that a BOR has occurred. The BOR circuit, if enabled, continues to operate while in Sleep or Idle modes and resets the device should VDD fall below the BOR threshold voltage. VDD CEFC BOR: Brown-out Reset (BOR) Preliminary When BOR is disabled, an external POR circuit should be used to ensure that the device remains in Reset until the minimum VDD is reached. DS70616C-page 437 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 29.4 29.4.2 Watchdog Timer (WDT) For dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices, the WDT is driven by the LPRC Oscillator. When the WDT is enabled, the clock source is also enabled. 29.4.1 PRESCALER/POSTSCALER The nominal WDT clock source from LPRC is 32 kHz. This feeds a prescaler that 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 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 Note: SLEEP AND IDLE MODES If the WDT is enabled, it continues to run during Sleep or Idle modes. When the WDT time-out occurs, the device wakes the device and code execution continues from where the PWRSAV instruction was executed. The corresponding SLEEP or IDLE bits (RCON<3,2>) needs to be cleared in software after the device wakes up. 29.4.3 ENABLING WDT 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 application 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. 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. The CLRWDT and PWRSAV instructions clear the prescaler and postscaler counts when executed.

Detailed information on this interface is provided in future revisions of the document. Note: 29.6 Refer to Section 24. "Programming and Diagnostics" (DS70608) of the "dsPIC33E/PIC24E Family Reference Manual" for further information on usage, configuration and operation of the JTAG interface. In-Circuit Serial Programming The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices can be serially programmed while in the end application circuit. This is done with two lines for clock and data and three other lines for power, ground and the programming sequence. Serial programming allows customers to manufacture boards with unprogrammed devices and then program the digital signal controller just before shipping the product. Serial programming also allows the most recent firmware or a custom firmware to be programmed. Refer to the "dsPIC33E/PIC24E Flash Programming Specification" (DS70619) for details about In-Circuit Serial Programming (ICSP). Code Protection and CodeGuardTM Security The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices offer basic implementation of CodeGuard Security that supports only General Segment (GS) security. 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 IPs reside on the single chip. The code protection features vary depending on the actual dsPIC33E implemented. The following sections provide an overview of these features. The dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 devices do not support Boot Segment (BS), Secure Segment (SS), and RAM protection. Note: Refer to Section 23. "CodeGuardTM Security" (DS70624) of the "dsPIC33E/ PIC24E Family Reference Manual" for further information on usage, configuration and operation of CodeGuard Security. Any of the three pairs of programming clock/data pins can be used: * PGEC1 and PGED1 * PGEC2 and PGED2 * PGEC3 and PGED3 29.7 In-Circuit Debugger When MPLAB(R) ICD 3 or REAL ICETM 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 of the three pairs of debugging clock/data pins can 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 connections to MCLR, VDD, VSS, and the PGECx/PGEDx 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.

It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the related section of the "dsPIC33E/PIC24E Family Reference Manual", which is available from the Microchip web site (www.microchip.com). The dsPIC33EP instruction set is almost identical to that of the dsPIC30F and dsPIC33F. The PIC24EP instruction set is almost identical to that of the PIC24F and PIC24H. 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 30-1 lists the general symbols used in describing the instructions. The dsPIC33E instruction set summary in Table 30-2 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 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 can use some of the following operands: * A literal value to be loaded into a W register or file register (specified by `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 MAC class of DSP instructions can use some of the following operands: * The accumulator (A or B) to be used (required operand) * The W registers to be used as the two operands * The X and Y address space prefetch operations * The X and Y address space prefetch destinations * The accumulator write back destination The other DSP instructions do not involve any multiplication and can include: * The accumulator to be used (required) * The source or destination operand (designated as Wso or Wdo, respectively) with or without an address modifier * The amount of shift specified by a W register `Wn' or a literal value The control instructions can use some of the following operands: However, word or byte-oriented file register instructions have two operands: * A program memory address * The mode of the table read and table write instructions * The file register specified by the value `f' * The destination, which could be either the file register `f' or the W0 register, which is denoted as `WREG' (c) 2009-2011 Microchip Technology Inc. Preliminary DS70616C-page 441 dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814 Most instructions are a single word. Certain doubleword instructions are designed to provide all the required information 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 executes as a NOP. The double-word instructions execute in two instruction cycles. 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, or a PSV or table read is performed. In these cases, the execution takes multiple instruction cycles TABLE 30-1: with the additional instruction cycle(s) executed as a NOP. 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 two-word instruction. Moreover, double-word moves require two cycles. Note: For more details on the instruction set, refer to the "16-bit MCU and DSC Programmer's Reference Manual" (DS70157).
