Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

2.2 Decoupling Capacitors

The use of decoupling capacitors on every pair of

power supply pins, such as VDD, VSS, VUSB, AVDD

and AVSS is required.

Consider the following criteria when using decoupling

capacitors:

•Value and type of capacitor: Recommendation

of 0.1 µF (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 freque nc y nois e : If the board is

experiencing high frequency noise, above tens of

MHz, add a second ceramic-type capacitor in par-

allel to the above described decoupling capacitor.

The value of the second capacitor can be in the

range of 0.01 µF to 0.001 µF. Place this second

capacitor next to the primary decoupling capaci-

tor. In high-speed circuit designs, consider imple-

menting a decade pair of capacitances as close to

the power and ground pins as possible. For exam-

ple, 0.1 µF in parallel with 0.001 µF.

•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.

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 compre-

hensive reference source. To comple-

ment 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.

Note: The AVDD and AVSS pins must be

connected independent of the ADC

voltage reference source.

2.2.1 TANK CAPACITORS

On boards with power traces running longer than six

inches in length, it is suggested to use a tank capacitor

for integrated circuits including DSCs to supply a local

power source. The value of the tank capacitor should

be determined based on the trace resistance that con-

nects the power supply source to the device, and the

maximum current drawn by the device in the applica-

tion. In other words, select the tank capacitor so that it

meets the acceptable voltage sag at the device. Typical

values range from 4.7 µF to 47 µF.

2.3 CPU Logic Filter Capacitor

Connection (VCAP)

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 µF (10 µF 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.

2.4 Master Clear (MCLR) Pin

The MCLR pin provides two specific device

functions:

• Device Reset

• Device Programming and Debugging

During device programming and debugging, the

resistance and capacitance that can be added to the

pin must be considered. Device programmers and

debuggers drive the MCLR pin. Consequently,

specific voltage levels (VIH and VIL) and fast signal

transitions must not be adversely affected. Therefore,

specific values of R and C will need to be adjusted

based on the application and PCB requirements.

For example, as shown in Figure 2-2, it is

recommended that the capacitor C, be isolated from

the MCLR pin during programming and debugging

operations.

Place the components as shown in Figure 2-2 within

one-quarter inch (6 mm) from the MCLR pin.

2.5 ICSP Pins

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 con-

nector 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 communi-

cations 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® PICkit™ 3, MPLAB ICD 3, or MPLAB REAL

ICE™.

For more information on MPLAB ICD 3 and MPLAB

REAL ICE connection requirements, refer to the

following documents that are available on the

Microchip web site.

2.6 External Oscillator Pins

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.

2.7 Oscillator Value Conditions on

Device Start-up

If the PLL of the target device is enabled and

configured for the device start-up oscillator, the

maximum oscillator source frequency must be limited

to 3 MHz < FIN < 5.5 MHz to comply with device PLL

start-up conditions. This means that if the external

oscillator frequency is outside this range, the

application must start-up in the FRC mode first. The

default PLL settings after a POR with an oscillator

frequency outside this range will violate the device

operating speed.

Once the device powers up, the application firmware

can initialize the PLL SFRs, CLKDIV and PLLDBF to a

suitable value, and then perform a clock switch to the

Oscillator + PLL clock source. Note that clock switching

must be enabled in the device Configuration Word.

2.8 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.

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

3.0 CPU

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 execu-

tion 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 instruc-

tions. These two instruction classes are seamlessly

integrated into the architecture and execute from a sin-

gle execution unit. The instruction set includes many

addressing modes and was designed for optimum

C compiler efficiency.

3.3 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-data-

space 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 Manua l” 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 boundary-

checking 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 Bit-

Reverse 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.

dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 is shown in Figure 3-2. All

registers in the programmer’s model are memory

mapped and can be manipulated directly by

instructions. Table 3-1 lists a description of each

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

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. 32-bit signed/16-bit signed divide

2. 32-bit unsigned/16-bit unsigned divide

3. 16-bit signed/16-bit signed divide

4. 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.

3.8 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 accumula-

tor-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 (ACC-

SAT)

4.0 MEMORY ORGANIZATION

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 architecture features sepa-

rate program and data memory spaces and buses. This

architecture also allows the direct access of program

memory from the data space during code execution.

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.

4.1.1 PROGRAM MEMORY

ORGANIZATION

The program memory space is organized in word-

addressable 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.

4.1.2 INTERRUPT AND TRAP VECTORS

All dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 devices reserve the

addresses between 0x00000 and 0x000200 for hard-

coded 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 mem-

ory 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.

A more detailed discussion of the interrupt vector

tables is provided in Section 7.1 “Interrupt Vector

Table”.

4.2 Data Add ress Space

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 CPU has a separate 16-bit

wide data memory space. The data space is accessed

using separate Address Generation Units (AGUs) for

read and write operations. 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® 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

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.

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’.

4.2.4 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 abso-

lute 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

Note: 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.

4.2.5 X AND Y DATA SPACES

The dsPIC33EPXXXMU806/810/814 core has two

data spaces, X and Y. 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).

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.

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).

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.

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.

4.2.6 DMA RAM

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 trans-

ferred 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.

When the CPU and the DMA controller attempt to

concurrently write to the same DMA RAM location, the

hardware ensures that the CPU is given precedence in

accessing the DMA RAM location. Therefore, the DMA

RAM provides a reliable means of transferring DMA

data without ever having to stall the CPU.

Note 1: DMA RAM can be used for general

purpose data storage if the DMA function

is not required in an application.

2: On PIC24EPXXXGU810/814 devices,

DMA RAM is located at the end of X data

RAM and is part of X data space.

4.2.7 PAGED MEMORY SCHEME

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 post-

modified 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

(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.

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.

EXAMPLE 4-2: EXTENDED DATA SPACE (EDS) WRITE ADDRESS GENERATION

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.

RAM

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

Allocating different page registers for read and write

access allows the architecture to support data

movement between different pages in data memory.

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

not include register offset addressing.

In general, when an overflow is detected, the DSxPAG

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. Tab le 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

4.2.8 EXTENDED X DATA SPACE

The lower half of the base address space range

between 0x0000 and 0x7FFF is always accessible

regardless of the contents of the data space page

registers. It is indirectly addressable through the

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.

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.

For more information of the PSV page access using

data space page registers refer to 4.5 “Program

Space Visibility from Data Space” in Section 4.

PIC24E Family Reference Manual”.

4.2.9 EDS ARBITRATION AND BUS

MASTER PRIORITY

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.

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,

respectively (M1 is reserved and cannot be used). 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.

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.

4.2.10 SOFTWARE STACK

The W15 register serves as a dedicated software Stack

Pointer (SP) and is automatically modified by exception

processing, subroutine calls and returns; however,

W15 can be referenced by any instruction in the same

manner as all other W registers. This simplifies

reading, writing and manipulating of the Stack Pointer

(for example, creating stack frames).

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 post-

increments 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.

FIGURE 4-9: CALL STACK FRAME

4.3 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

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 reg-

ister, 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: To protect against misaligned stack

accesses, W15<0> is fixed to ‘0’ by the

hardware.

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.

Note: Not all instructions support all the

addressing modes given above. Individ-

ual instructions can support different

subsets of these addressing modes.

4.3.3 MOVE AND ACCUMULATOR

INSTRUCTIONS

Move instructions (dsPIC33EPXXXMU806/810/814

and PIC24EPXXXGU810/814) and the DSP accumula-

tor class of instructions (dsPIC33EPXXXMU806/810/

814 only) provide a greater degree of addressing flexi-

bility than other instructions. In addition to the address-

ing 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.

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

4.3.4 MAC INSTRUCTIONS

(dsPIC33EPXXXMU806/810/814

DEVICES ONLY)

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.

In summary, the following addressing modes are

supported by the MAC class of instructions:

• Register Indirect

• Register Indirect Post-Modified by 2

• Register Indirect Post-Modified by 4

• Register Indirect Post-Modified by 6

• Register Indirect with Register Offset (Indexed)

4.3.5 OTHER INSTRUCTIONS

Besides the addressing modes outlined previously, some

instructions use literal constants of various sizes. For

example, BRA (branch) instructions use 16-bit signed

literals to specify the branch destination directly, whereas

the DISI instruction uses a 14-bit unsigned literal field. In

some instructions, 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.

Addressing Mode Description

to form the EA.

(Register Indexed)

The sum of Wn and Wb forms the EA.

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).

Note: Not all instructions support all the

addressing modes given above. Individual

instructions may support different subsets

of these addressing modes.

Note: Register Indirect with Register Offset

Addressing mode is available only for W9

(in X space) and W11 (in Y space).

4.4 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 config-

ured to operate in only one direction as there are

certain restrictions on the buffer start address (for incre-

menting 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).

4.4.1 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 Ta ble 4-1).

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

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>.

4.4.3 MODULO ADDRESSING

APPLICABILITY

Modulo Addressing can be applied to the Effective

Address (EA) calculation associated with any W

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.

4.5 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.

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.

4.5.1 BIT-REVERSED ADDRESSING

IMPLEMENTATION

Bit-Reversed Addressing mode is enabled in any of

these situations:

• BWM bits (W register selection) in the MODCON

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

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.

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.

When enabled, Bit-Reversed Addressing is executed

only for Register Indirect with Pre-Increment or Post-

Increment 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

addition, as word-sized data is a requirement, the LSb

of the EA is ignored (and always clear).

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.

Note: The modulo corrected effective address is

written back to the register only when Pre-

Modify 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

word-sized data (LSb of every EA is

always clear). The XB value is scaled

accordingly to generate compatible (byte)

addresses.

Note: 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.

4.6 Interfacing Program and Data

Memory Spaces

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 architecture uses a 24-bit-

wide program space and a 16-bit-wide data space. The

architecture is also a modified Harvard scheme, mean-

ing 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 instructions allow an application to read or write

to small areas of the program memory. This capability

makes the method ideal for accessing data tables that

need to be updated 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.

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-bit-

wide 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>).

- 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 instruc-

tion. 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

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.

5.0 FLASH PROGRAM MEMORY

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 Programming™ (ICSP™)

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

pin pairs: PGECx/PGEDx), and three other lines for

power (VDD), ground (VSS) and Master Clear (MCLR).

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.

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.

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.

5.2 RTSP Operation

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 Flash program memory

array is organized into rows of 128 instructions or 384

bytes. 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 pro-

gramming 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 eras-

ing 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).

EQUATION 5-1: PROGRAMMING TIME

For example, if the device is operating at +125°C, the

FRC accuracy will be ±5%. If the TUN<5:0> bits (see

write time is equal to Equation 5-2.

EQUATION 5-2: MINIMUM ROW WRITE

TIME

The maximum row write time is equal to Equation 5-3.

EQUATION 5-3: MAXIMUM ROW WRITE

TIME

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

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.

6.0 RESETS

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

A simplified block diagram of the Reset module is

shown in Figure 6-1.

Any active source of Reset will make the SYSRST sig-

nal 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.

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.

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 24-

bit-wide address. The value programmed into each

interrupt vector location is the starting address of the

associated Interrupt Service Routine (ISR).

Interrupt vectors are prioritized in terms of their natural

priority. This priority is linked to their position in the

vector table. 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 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 compre-

hensive reference source. To comple-

ment the information in this data sheet,

refer to Section 6. “Interrupts”

(DS70600) 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.

Note: 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.

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

7.3 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 INTCON1 THROUGH INTCON4

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.

The INTCON4 register contains the software

generated hard trap status bit (SGHT).

7.3.2 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.

7.3.4 IPCx

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.

The interrupt sources are assigned to the IFSx, IECx

and IPCx registers in the same sequence as they are

listed in Tab l e 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.

Level. The value in parentheses indicates the IPL, if IPL<3> = 1.

8.0 DIRECT MEMORY ACCESS

(DMA)

The DMA controller transfers data between peripheral

data registers and data space SRAM. The

dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 DMA subsystem uses dual-

ported 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

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:

• ECAN™

• 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.

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 provides these functional

capabilities:

• Up to 15 DMA channels

• Register Indirect With Post-increment Addressing

mode

• Register Indirect Without Post-increment

Addressing mode

• Peripheral Indirect Addressing mode (peripheral

generates destination address)

• CPU interrupt after half or full-block transfer com-

plete

• 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 trans-

fer complete)

• DMA request for each channel can be selected

from any supported interrupt source

8.1 DMAC Registers

Each DMAC Channel x (where x = 0 through 14)

contains the following registers:

• 16-bit DMA Channel Control register (DMAxCON)

• 16-bit DMA Channel IRQ Select register

(DMAxREQ)

• 32-bit DMA RAM Primary Start Address register

(DMAxSTA)

• 32-bit DMA RAM Secondary Start Address

• 16-bit DMA Peripheral Address register (DMAxPAD)

• 14-bit DMA Transfer Count register (DMAxCNT)

Additional status registers (DMAPWC, DMARQC,

DMAPPS, DMALCA, and DSADR) are common to all

DMAC channels. These status registers provide infor-

mation on write and request collisions, as well as on

last address and channel access information.

The interrupt flags (DMAxIF) are located in an IFSx

interrupt enable control bits (DMAxIE) are located in

an IECx register in the interrupt controller, and the

corresponding interrupt priority control bits (DMAxIP)

are located in an IPCx register in the interrupt

controller.

9.0 OSCILLATOR CONFIGURATION The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 oscillator system provides:

• Four external and internal oscillator options

• Auxiliary oscillator that provides clock source to

the USB module

• On-chip Phase-Locked Loop (PLL) to boost inter-

nal operating frequency on select internal and

external oscillator sources

• On-the-fly clock switching between various clock

sources

• Doze mode for system power savings

• Fail-Safe Clock Monitor (FSCM) that detects clock

failure and permits safe application recovery or

shutdown

• Nonvolatile Configuration bits for clock source

selection

A simplified diagram of the oscillator system is shown

in Figure 9-1.

9.1 CPU Clocking System

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 family of devices provide

seven system clock options:

• Fast RC (FRC) Oscillator

• FRC Oscillator with Phase-Locked Loop (PLL)

• Primary (XT, HS or EC) Oscillator

• Primary Oscillator with PLL

• Secondary (LP) Oscillator

• Low-Power RC (LPRC) Oscillator

• FRC Oscillator with postscaler

10.0 POWER-SAVING FEATURES

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.

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

Combinations of these methods can be used to selec-

tively tailor an application’s power consumption while

still maintaining critical application features, such as

timing-sensitive communications.

10.1 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” .

10.2 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.

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:

• 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.

The device wakes up from Sleep mode on any of the

these events:

• 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.

EXAMPLE 10-1: PWRSAV INSTRUCTION SYNTAX

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 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.

Note: SLEEP_MODE and IDLE_MODE are con-

stants defined in the assembler include

file for the selected device.

PWRSAV #IDLE_MODE ; Put the device into IDLE mode

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 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.

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 Peripheral Module Disable

The Peripheral Module Disable (PMD) registers

provide a method to disable a peripheral module by

stopping all clock sources supplied to that module.

When a peripheral is disabled 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® DSC

variant. If the peripheral is present in the device, it is

enabled in the PMD register by default.

Note: If a PMD bit is set, the corresponding

module is disabled after a delay of 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 regis-

ters are already configured to enable

module operation).

11.0 I/O PORTS

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

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

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.

11.1.1 OPEN-DRAIN CONFIGURATION

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 Dia grams” 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 I/O PORT WRITE/READ TIMING

One instruction cycle is required between a port

direction change or port write operation and a read

operation of the same port. Typically this instruction

would be an NOP, as shown in Example 11-1.

11.3 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-of-

state 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.

EXAMPLE 11-1: PORT WRITE/READ

Note: Pull-ups and pull-downs on change notifi-

cation pins should always be disabled

when the port pin is configured as a digital

output.

11.4 Peripheral Pin Select

A major challenge in general purpose devices is provid-

ing the largest possible set of peripheral features while

minimizing the conflict of features on I/O pins. The chal-

lenge 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 oper-

ates over a fixed subset of digital I/O pins. Users may

independently map the input and/or output of most dig-

ital 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 pur-

pose 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 spe-

cial 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 mod-

ules with analog inputs, such as the A/D converter.

A key difference between remappable and non-remap-

pable 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.

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 con-

trolled, 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-select-

able 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

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 corre-

sponds to the maximum number of peripheral pin selec-

tions supported by the device.

For example, Figure 11-2 illustrates remappable pin

selection for the U1RX input.

to peripheral

RPn/RPIn

Note: For input only, peripheral pin select functionality

does not have priority over TRISx settings.

Therefore, when configuring RPn/RPIn pin for

input, the corresponding bit in the TRISx register

must also be configured for input (set to ‘1’).

11.4.3.2 Output Mapping

In contrast to inputs, the outputs of the peripheral pin

select options are mapped on the basis of the pin. 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 periph-

erals, 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 out-

puts remain disconnected from all output pins by

default.

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 inter-

peripheral 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.

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 hardware-

enforced 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-to-

many 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.

EXAMPLE 11-1: CONNECTING IC1 TO THE HOME1 DIGITAL FILTER INPUT ON PIN 3 OF THE

dsPIC33EP512MU810 DEVICE

RPINR15 = 0x5600; /* Connect the QEI1 HOME1 input to RP86 (pin 3) */

RPINR7 = 0x009; /* Connect the IC1 input to the digital filter on the FHOME1 input */

QEI1IOC = 0x4000; /* Enable the QEI digital filter */

QEI1CON = 0x8000; /* Enable the QEI module */

12.0 TIMER1

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.

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.

The unique features of Timer1 allow it to be used for

Real Time Clock (RTC) applications. A block diagram

of Timer1 is shown in Figure 12-1.

The Timer1 module can operate in one of the following

modes:

• Timer mode

• Gated Timer mode

• Synchronous Counter mode

• Asynchronous Counter mode

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.

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>

Timer control bit setting for different operating modes

are given in the Table 12-1.

13.0 TIMER2/3, TIMER4/5, T IMER6/7

AND TIMER8/9

The Timer2/3, Timer4/5, Timer6/7 and Timer8/9

modules are 32-bit timers, which can also be

configured as four independent 16-bit timers with

selectable operating modes.

As a 32-bit timer, Timer2/3, Timer4/5, Timer6/7 and

Timer8/9 operate in three modes:

• Two Independent 16-bit Timers (e.g., Timer2 and

Timer3) with all 16-bit operating modes (except

Asynchronous Counter mode)

• Single 32-bit Timer

• Single 32-bit Synchronous Counter

They also support these features:

• Timer Gate Operation

• Selectable Prescaler Settings

• Timer Operation during Idle and Sleep modes

• Interrupt on a 32-bit Period Register Match

• Time Base for Input Capture and Output Compare

Modules (Timer2 and Timer3 only)

• ADC1 Event Trigger (Timer2/3 only)

• ADC2 Event Trigger (Timer4/5 only)

Individually, all eight of the 16-bit timers can function as

synchronous timers or counters. They also offer the

features listed above, except for the event trigger; this

is implemented only with Timer2/3. The operating

modes and enabled features are determined by setting

the appropriate bit(s) in the T2CON, T3CON, T4CON,

T5CON, T6CON, T7CON, T8CON and T9CON

registers. T2CON, T4CON, T6CON and T8CON are

shown in generic form in Register 13-1. T3CON,

T5CON, T7CON and T9CON are shown in

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.

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.

of the dsPIC33EPXXXMU806/810/814

and PIC24EPXXXGU810/814 family of

devices. It is not intended to be a

comprehensive reference source. To

2: Some registers and associated bits

described in this section may not be

available on all devices. Refer to

Section 4.0 “Memory Organization” in

this data sheet for device-specific register

and bit information.

Note: 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.

Note: Only Timer2, 3, 4 and 5 can trigger a DMA

data transfer.

15.0 OUTPUT COMPARE The Output Compare module can select one of eight

available clock sources for its time base. 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.

16.0 HIGH-SPEED PWM MODULE

(dsPIC33EPXXXMU806/810/814

DEVICES ONLY)

The dsPIC33EPXXXMU806/810/814 devices support

a dedicated Pulse-Width Modulation (PWM) module

with up to 14 outputs.

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

• 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

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 dur-

ing 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.

18.0 SERIAL PERIPHERAL

INTERFACE (SPI)

The SPI module is a synchronous serial interface use-

ful for communicating with other peripheral or micro-

controller 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.

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 device family offers four SPI

modules on a single device. These modules, which are

designated as SPI1, SPI2, SPI3 and SPI4, are function-

ally 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.

The SPIx serial interface consists of four pins, as

follows:

• 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.

19.0 INTER-INTEGRATED

CIRCUIT™ (I2C™) The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 family of devices contain two

Inter-Integrated Circuit (I2C) modules: I2C1 and I2C2.

The I2C module provides complete hardware support

for both Slave and Multi-Master modes of the I2C serial

communication standard, with a 16-bit interface.

The I2C module has a 2-pin interface:

• The SCLx pin is clock.

• The SDAx pin is data.

The I2C module offers the following key features:

•I

2C interface supporting both Master and Slave

modes of operation.

•I

2C Slave mode supports 7 and 10-bit address.

•I

2C Master mode supports 7 and 10-bit address.

•I

2C port allows bidirectional transfers between

master and slaves.

• Serial clock synchronization for I2C port can be

used as a handshake mechanism to suspend and

resume serial transfer (SCLREL control).

•I

2C supports multi-master operation, detects bus

collision and arbitrates accordingly.

• IPMI support

• SMBus support

21.0 ENHANCED CAN (ECAN™)

MODULE

21.1 Overview

The Enhanced Controller Area Network (ECAN)

module is a serial interface, useful for communicat-

ing 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 implemen-

tation 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.

The ECAN module features are as follows:

• Implementation of the CAN protocol, CAN 1.2,

CAN 2.0A and CAN 2.0B

• Standard and extended data frames

• 0-8 bytes data length

• Programmable bit rate up to 1 Mbit/sec

• Automatic response to remote transmission

requests

• Up to eight transmit buffers with application speci-

fied 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

• DeviceNet™ 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 time-

stamping and network synchronization

• Low-power Sleep and Idle mode

The CAN bus module consists of a protocol engine and

message buffering/control. The CAN protocol engine

handles all functions for receiving and transmitting

messages on the CAN bus. Messages are transmitted

by first loading the appropriate data registers. Status

and errors can be checked by reading the appropriate

registers. Any message detected on the CAN bus is

checked for errors and then matched against filters to

see if it should be received and stored in one of the

receive registers.

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 21. “Enhanced

FIGURE 21-1: ECAN™ MODULE BLOCK DIAGRAM

21.2 Modes of Operation

The ECAN module can operate in one of several

operation modes selected by the user. These modes

include:

• Initialization mode

• Disable mode

• Normal Operation mode

• Listen Only mode

• Listen All Messages mode

• Loopback mode

Modes are requested by setting the REQOP<2:0> bits

(CiCTRL1<10:8>). Entry into a mode is Acknowledged

by monitoring the OPMODE<2:0> bits

(CiCTRL1<7:5>). The module 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 (ECAN™)” (DS70353) of the “dsPIC33E/

PIC24E Family Reference Manual” for more details on

ECAN.

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

22.0 USB ON-THE-GO (OTG)

MODULE

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

The USB module contains the analog and digital

components to provide a USB 2.0 full-speed and low-

speed 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.

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.

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 25. “USB On-

The-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.

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.

Note: Throughout this section, a bit that can only

be cleared by writing a ‘1’ to its location is

referred to as “Write ‘1’ to clear bit”. In reg-

ister descriptions, this function is indicated

by the descriptor, “K”.

23.0 10-BIT/12-BIT ANALOG-TO-

DIGITAL CONVERTER (ADC)

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.

The ADC2 module only supports 10-bit operation with

4 S&H.

23.1 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 ana-

log 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 23-2 provides a diagram of the

ADC conversion clock period.

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 16. “Analog-to-

Digital Converter (ADC)” (DS70621) of

the “dsPIC33E/PIC24E Family Refer-

ence 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.

Note: The ADC1 module needs to be disabled

before modifying the AD12B bit.

25.0 COMP A RATOR MO DULE The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 Comparator module pro-

vides three comparators that can be configured in dif-

ferent 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.

26.0 REAL-TIME CLOCK AND

CALENDAR (RTCC)

This chapter discusses the Real-Time Clock and

Calendar (RTCC) module, available on

dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 devices, and its operation.

Some of the key features of this module are:

• 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 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 pro-

vide extended battery lifetime while keeping track of

time.

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.

26.1 Writing to the RTCC Timer

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

set. Setting the RTCWREN bit allows writes to the

RTCC registers. Conversely, clearing the RTCWREN

bit prevents writes.

To set the RTCWREN bit, the following procedure must

be executed. The RTCWREN bit can be cleared at any

time:

1. Write 0x55 to NVMKEY.

2. Write 0xAA to NVMKEY.

3. 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

Note: To allow the RTCC module to be clocked

by the secondary crystal oscillator, the

Secondary Oscillator Enable (LPOSCEN)

bit in the Oscillator Control

(OSCCON<1>) register must be set. For

further details, refer to

Section 7. “Oscillator” (DS70580) in the

'dsPIC33E/PIC24E Family Reference

Manual'.

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.

For example, consider two CRC polynomials, one a 16-

bit equation and the other a 32-bit equation:

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 poly-

nomial 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.

28.0 PARALLEL MASTER PORT

(PMP) The Parallel Master Port (PMP) module is a parallel

8-bit I/O module, specifically designed to communi-

cate with a wide variety of parallel devices, such as

communication peripherals, LCDs, external memory

devices and microcontrollers. Because the interface

to parallel peripherals varies significantly, the PMP is

highly configurable.

Key features of the PMP module include:

• Eight Data Lines

• Up to 16 Programmable Address Lines

• Up to two Chip Select Lines

• Programmable Strobe Options:

- Individual read and write strobes, or

- Read/Write strobe with enable strobe

• Address Auto-Increment/Auto-Decrement

• Programmable Address/Data Multiplexing

• Programmable Polarity on Control Signals

• Legacy Parallel Slave Port (PSP) Support

• Enhanced Parallel Slave Support:

- Address support

- 4-byte deep auto-incrementing buffer

• Programmable Wait States

29.0 SPECIAL FEATURES

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:

• Flexible configuration

• Watchdog Timer (WDT)

• Code Protection and CodeGuard™ Security

• JTAG Boundary Scan Interface

• In-Circuit Serial Programming™ (ICSP™)

• In-Circuit emulation

29.1 Configuration Bits

The dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 devices provide nonvolatile

memory implementation for device Configuration bits.

Refer to Section 30. “Device Configuration”

(DS70618) of the “dsPIC33E/PIC24E Family

Reference Manual” for more information on this

implementation.

The Configuration bits can be programmed (read as

‘0’), or left unprogrammed (read as ‘1’), to select

various device configurations. These bits are mapped

starting at program memory location 0xF80000.

The 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.

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.

Note: 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

29.2 On-Chip Voltage Regulator

All of the dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 devices power their core

digital logic at a nominal 1.8V. 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 sta-

bility of the regulator. The recommended value for the

filter capacitor is provided in Table 32-13 located in

Section 32.0 “Electrical Characteristics ”.

FIGURE 29-1: CONNECTIONS FOR THE

ON-CHIP VOLTAGE

REGULATOR(1)

29.3 BOR: Brown-out Reset (BOR)

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 brown-

out condition occurs. Brown-out conditions are gener-

ally 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 exces-

sive current draw when a large inductive load is turned

on). The BOR feature is enabled by setting the BOREN

Configuration bit (FPOR<3>).

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.

The BOR Status bit (RCON<1>) is set to indicate that a

BOR has occurred. The BOR circuit, if enabled, contin-

ues to operate while in Sleep or Idle modes and resets

the device should VDD fall below the BOR threshold

voltage.

Note: It is important for the low-ESR capacitor to

be placed as close as possible to the VCAP

pin.

Note 1: These are typical operating voltages. Refer

to Section TABLE 32-13: “Internal Volt-

age Regulator Specifications” located in

Section 32.1 “DC Characteristics” for

the full operating ranges of VDD and VCAP.

be placed as close as possible to the VCAP

pin.

29.4 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 selec-

tion of 16 settings, from 1:1 to 1:32,768. Using the pres-

caler 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

29.4.2 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 corre-

sponding 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.

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.

FIGURE 29-2: WDT BLOCK DIAGRAM

Note: The CLRWDT and PWRSAV instructions

clear the prescaler and postscaler counts

when executed.

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.

29.5 JTAG Interface

dsPIC33EPXXXMU806/810/814 and

PIC24EPXXXGU810/814 devices implement a JTAG

interface, which supports boundary scan device

testing. Detailed information on this interface is

provided in future revisions of the document.

29.6 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).

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® ICD 3 or REAL ICE™ is selected as a

debugger, the in-circuit debugging functionality is

enabled. This function allows simple debugging func-

tions when used with MPLAB IDE. Debugging function-

ality 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.

29.8 Code Protection and

CodeGuard™ 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 24. “Programming and

Diagnostics” (DS70608) of the

“dsPIC33E/PIC24E Family Reference

Manual” for further information on usage,

configuration and operation of the JTAG

interface.

Note: Refer to Section 23. “CodeGuard™

Security” (DS70624) of the “dsPIC33E/

PIC24E Family Reference Manual” for

further information on usage,

configuration and operation of

CodeGuard Security.

30.0 INSTRUCTION SET SUMMARY

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 Ta b l e 3 0 - 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

• The second source operand, which is typically a

• The destination of the result, which is typically a

However, word or byte-oriented file register instructions

have two operands:

• The file register specified by the value ‘f’

• The destination, which could be either the file

‘WREG’

Most bit-oriented instructions (including simple rotate/

shift instructions) have two operands:

• The W register (with or without an address

modifier) or file register (specified by the value of

‘Ws’ or ‘f’)

• The bit in the W register or file register (specified

by a literal value or indirectly by the contents of

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

• 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

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:

• A program memory address

• The mode of the table read and table write

instructions

Note: 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).

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

Most instructions are a single word. Certain double-

word 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 exe-

cuted 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

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”

Evaluation Kits, and Starter Kits

31.1 MPLAB Integrated Development

Environment Software

The MPLAB IDE software brings an ease of software

development previously unseen in the 8/16/32-bit

microcontroller market. The MPLAB IDE is a Windows®

operating system-based application that contains:

• A single graphical interface to all debugging tools

- Simulator

- Programmer (sold separately)

- In-Circuit Emulator (sold separately)

- In-Circuit Debugger (sold separately)

• A full-featured editor with color-coded context

• A multiple project manager

• Customizable data windows with direct edit of

contents

• High-level source code debugging

• Mouse over variable inspection

• Drag and drop variables from source to watch

windows

• Extensive on-line help

• Integration of select third party tools, such as

IAR C Compilers

The MPLAB IDE allows you to:

• Edit your source files (either C or assembly)

• One-touch compile or assemble, and download to

emulator and simulator tools (automatically

updates all project information)

• Debug using:

- Source files (C or assembly)

- Mixed C and assembly

- Machine code

MPLAB IDE supports multiple debugging tools in a

single development paradigm, from the cost-effective

simulators, through low-cost in-circuit debuggers, to

full-featured emulators. This eliminates the learning

curve when upgrading to tools with increased flexibility

and power.

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

31.2 MPLAB C Compilers for Various

Device Families

The MPLAB C Compiler code development systems

are complete ANSI C compilers for Microchip’s PIC18,

PIC24 and PIC32 families of microcontrollers and the

dsPIC30 and dsPIC33 families of digital signal control-

lers. These compilers provide powerful integration

capabilities, superior code optimization and ease of

use.

For easy source level debugging, the compilers provide

symbol information that is optimized to the MPLAB IDE

debugger.

31.3 HI-TECH C for Various Device

Families

The HI-TECH C Compiler code development systems

are complete ANSI C compilers for Microchip’s PIC

family of microcontrollers and the dsPIC family of digital

signal controllers. These compilers provide powerful

integration capabilities, omniscient code generation

and ease of use.

For easy source level debugging, the compilers provide

symbol information that is optimized to the MPLAB IDE

debugger.

The compilers include a macro assembler, linker, pre-

processor, and one-step driver, and can run on multiple

platforms.

31.4 MPASM Assembler

The MPASM Assembler is a full-featured, universal

macro assembler for PIC10/12/16/18 MCUs.

The MPASM Assembler generates relocatable object

files for the MPLINK Object Linker, Intel® standard HEX

files, MAP files to detail memory usage and symbol

reference, absolute LST files that contain source lines

and generated machine code and COFF files for

debugging.

The MPASM Assembler features include:

• Integration into MPLAB IDE projects

• User-defined macros to streamline

assembly code

• Conditional assembly for multi-purpose

source files

• Directives that allow complete control over the

assembly process

31.5 MPLINK Object Linker/

MPLIB Object Librarian

The MPLINK Object Linker combines relocatable

objects created by the MPASM Assembler and the

MPLAB C18 C Compiler. It can link relocatable objects

from precompiled libraries, using directives from a

linker script.

The MPLIB Object Librarian manages the creation and

modification of library files of precompiled code. When

a routine from a library is called from a source file, only

the modules that contain that routine will be linked in

with the application. This allows large libraries to be

used efficiently in many different applications.

The object linker/library features include:

• Efficient linking of single libraries instead of many

smaller files

• Enhanced code maintainability by grouping

related modules together

• Flexible creation of libraries with easy module

listing, replacement, deletion and extraction

31.6 MPLAB Assembler, Linker and

Librarian for Various Device

Families

MPLAB Assembler produces relocatable machine

code from symbolic assembly language for PIC24,

PIC32 and dsPIC devices. MPLAB C Compiler uses

the assembler to produce its object file. The assembler

generates relocatable object files that can then be

archived or linked with other relocatable object files and

archives to create an executable file. Notable features

of the assembler include:

• Support for the entire device instruction set

• Support for fixed-point and floating-point data

• Command line interface

• Rich directive set

• Flexible macro language

• MPLAB IDE compatibility

dsPIC33EPXXXMU806/810/814 and PIC24EPXXXGU810/814

31.7 MPLAB SIM Software Simulator

The MPLAB SIM Software Simulator allows code

development in a PC-hosted environment by simulat-

ing the PIC MCUs and dsPIC® DSCs on an instruction

level. On any given instruction, the data areas can be

examined or modified and stimuli can be applied from

a comprehensive stimulus controller. Registers can be

logged to files for further run-time analysis. The trace

Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.

2: Instruction cycle period (TCY) equals two times the input oscillator time base period. All specified values

are based on characterization data for that particular oscillator type under standard operating conditions

with the device executing code. Exceeding these specified limits may result in an unstable oscillator

operation and/or higher than expected current consumption. All devices are tested to operate at “Min”

values with an external clock applied to the OSC1 pin. When an external clock input is used, the “Max”

cycle time limit is “DC” (no clock) for all devices.

3: Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin.

4: This parameter is characterized, but not tested in manufacturing.
