2.0 GUIDELINES FOR GETTING

STARTED WITH 32-BIT MCUS

2.1 Basic Connection Requirements

Getting started with the PIC32MX1XX/2XX family of

32-bit Microcontrollers (MCUs) requires attention to a

minimal set of device pin connections before proceed-

ing with development. The following is a list of pin

names, which must always be connected:

• All VDD and VSS pins (see 2.2 “Decoupling

Capacitors”)

• All AVDD and AVSS pins, even if the ADC module is

not used (see 2.2 “Decoupling Capacitors”)

•V

CAP pin (see 2.3 “Capacitor on Internal Voltage

Regulator (VCAP)”)

•MCLR

pin (see 2.4 “Master Clear (MCLR) Pin”)

• PGECx/PGEDx pins, used for In-Circuit Serial

Programming (ICSP™) and debugging purposes

• (see 2.5 “ICSP Pins”)

• OSC1 and OSC2 pins, when external oscillator

source is used (see 2.7 “External Oscillator Pins”)

The following pin may be required, as well:

•V

REF+/VREF- pins – used when external voltage

reference for the ADC module is implemented.

2.2 Decoupling Capacitors

The use of decoupling capacitors on power supply

pins, such as VDD, VSS, AVDD and AVSS is required.

See Figure 2-1.

Consider the following criteria when using decoupling

capacitors:

•Value and type of capacitor: A value of 0.1 µF

(100 nF), 10-20V is recommended. The capacitor

should be a low Equivalent Series Resistance (low-

ESR) capacitor and have resonance frequency in

the range of 20 MHz and higher. It is further

recommended that ceramic capacitors be used.

•Placement on the printed circuit board: The

decoupling capacitors should be placed as close to

the pins as possible. It is recommended that the

capacitors be placed 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, upward of 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 capacitor.

In high-speed circuit designs, consider implement-

ing a decade pair of capacitances as close to the

power and ground pins as possible. For example,

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 decou-

pling 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.

FIGURE 2-1: RECOMMENDED

MINIMUM CONNECTION

2.2.1 BULK CAPACITORS

The use of a bulk capacitor is recommended to improve

power supply stability. Typical values range from 4.7 µF

to 47 µF. This capacitor should be located as close to

the device as possible.

Note 1: This data sheet summarizes the features

of the PIC32MX1XX/2XX family 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

“PIC32 Family Reference Manual”, which

is available from the Microchip web site

(www.microchip.com/PIC32).

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, regardless of ADC use and

the ADC voltage reference source.

2.3 Capacitor on Internal Voltage

Regulator (VCAP)

2.3.1 INTERNAL REGULATOR MODE

A low-ESR (1 ohm) capacitor is required on the VCAP

pin, which is used to stabilize the internal voltage regu-

lator output. The VCAP pin must not be connected to

VDD, and must have a CEFC capacitor, with at least a

6V rating, connected to ground. The type can be

ceramic or tantalum. Refer to Section 29.0 “Electric al

Characteristics” for additional information on CEFC

specifications.

2.4 Master Clear (MCLR) Pin

The MCLR pin provides for two specific device

functions:

• Device Reset

• Device programming and debugging

Pulling The MCLR pin low generates a device Reset.

Figure 2-2 illustrates a typical MCLR circuit. 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 illustrated 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 illustrated in Figure 2-2 within

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

FIGURE 2-2: MCLR PIN CONNECTIONS

2.5 ICSP Pins

The PGECx and PGEDx pins are used for In-Circuit

Serial Programming™ (ICSP™) and debugging pur-

poses. It is recommended to keep the trace length

between the ICSP connector and the ICSP pins on the

device as short as possible. If the ICSP connector is

expected to experience an ESD event, a series resistor

is recommended, with the value in the range of a few

tens of Ohms, not to exceed 100 Ohms.

Pull-up resistors, series diodes and capacitors on the

PGECx and PGEDx pins are not recommended as they

will interfere with the programmer/debugger 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

2.6 JTAG

The TMS, TDO, TDI and TCK pins are used for testing

and debugging according to the Joint Test Action

Group (JTAG) standard. It is recommended to keep the

trace length between the JTAG connector and the

JTAG pins on the device as short as possible. If the

JTAG connector is expected to experience an ESD

event, a series resistor is recommended, with the value

in the range of a few tens of Ohms, not to exceed 100

Ohms.

Pull-up resistors, series diodes and capacitors on the

TMS, TDO, TDI and TCK pins are not recommended

as they will interfere with the programmer/debugger

communications to the device. If such discrete compo-

nents are an application requirement, they should be

removed from the circuit during programming and

debugging. Alternatively, refer to the AC/DC character-

istics 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.

Note 1: R 10 k is recommended. A suggested

starting value is 10 k. Ensure that the MCLR

pin VIH and VIL specifications are met.

2: R1  470 will limit any current flowing into

MCLR from the external capacitor C, in the

event of MCLR pin breakdown, due to

Electrostatic Discharge (ESD) or Electrical

Overstress (EOS). Ensure that the MCLR pin

VIH and VIL specifications are met.

3: The capacitor can be sized to prevent uninten-

tional Resets from brief glitches or to extend

the device Reset period during POR.

2.7 External Oscillator Pins

Many MCUs have options for at least two oscillators: a

high-frequency primary oscillator and a low-frequency

secondary oscillator (refer to Section 8.0 “Oscillator

Configuration” for details).

The oscillator circuit should be placed on the same side

of the board as the device. Also, place the oscillator cir-

cuit close to the respective oscillator pins, not exceed-

ing 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 illustrated in Figure 2-3.

2.8 Unused I/Os

Unused I/O pins should not be allowed to float as

inputs. They can be configured as outputs and driven

to a logic-low state.

Alternatively, inputs can be reserved by connecting the

pin to VSS through a 1k to 10k resistor and configuring

the pin as an input.

3.2 Architecture Overview

The MIPS32® M4K® processor core contains several

logic blocks working together in parallel, providing an

efficient high-performance computing engine. The

following blocks are included with the core:

• Execution Unit

• Multiply/Divide Unit (MDU)

• System Control Coprocessor (CP0)

• Fixed Mapping Translation (FMT)

• Dual Internal Bus interfaces

• Power Management

• MIPS16e Support

• Enhanced JTAG (EJTAG) Controller

3.2.1 EXECUTION UNIT

The MIPS32® M4K® processor core execution unit

implements a load/store architecture with single-cycle

ALU operations (logical, shift, add, subtract) and an

autonomous multiply/divide unit. The core contains

thirty-two 32-bit General Purpose Registers (GPRs)

used for integer operations and address calculation.

The register file consists of two read ports and one

write port and is fully bypassed to minimize operation

latency in the pipeline.

The execution unit includes:

• 32-bit adder used for calculating the data address

• Address unit for calculating the next instruction

address

• Logic for branch determination and branch target

address calculation

• Load aligner

• Bypass multiplexers used to avoid stalls when

executing instruction streams where data

producing instructions are followed closely by

consumers of their results

• Leading Zero/One detect unit for implementing

the CLZ and CLO instructions

• Arithmetic Logic Unit (ALU) for performing bitwise

logical operations

• Shifter and store aligner

3.2.2 MULTIPLY/DIVIDE UNIT (MDU)

The MIPS32® M4K® processor core includes a Multi-

ply/Divide Unit (MDU) that contains a separate pipeline

for multiply and divide operations. This pipeline oper-

ates in parallel with the Integer Unit (IU) pipeline and

does not stall when the IU pipeline stalls. This allows

MDU operations to be partially masked by system stalls

and/or other integer unit instructions.

The high-performance MDU consists of a 32x16 booth

recoded multiplier, result/accumulation registers (HI

and LO), a divide state machine, and the necessary

multiplexers and control logic. The first number shown

(‘32’ of 32x16) represents the rs operand. The second

number (‘16’ of 32x16) represents the rt operand. The

PIC32 core only checks the value of the latter (rt) oper-

and to determine how many times the operation must

pass through the multiplier. The 16x16 and 32x16

operations pass through the multiplier once. A 32x32

operation passes through the multiplier twice.

The MDU supports execution of one 16x16 or 32x16

multiply operation every clock cycle; 32x32 multiply

operations can be issued every other clock cycle.

Appropriate interlocks are implemented to stall the

issuance of back-to-back 32x32 multiply operations.

The multiply operand size is automatically determined

by logic built into the MDU.

Divide operations are implemented with a simple 1 bit

per clock iterative algorithm. An early-in detection

checks the sign extension of the dividend (rs) operand.

If rs is 8 bits wide, 23 iterations are skipped. For a 16-bit

wide rs, 15 iterations are skipped and for a 24-bit wide

rs, 7 iterations are skipped. Any attempt to issue a sub-

sequent MDU instruction while a divide is still active

causes an IU pipeline stall until the divide operation is

completed.

Table 3-1 lists the repeat rate (peak issue rate of cycles

until the operation can be reissued) and latency (num-

ber of cycles until a result is available) for the PIC32

core multiply and divide instructions. The approximate

latency and repeat rates are listed in terms of pipeline

clocks.

PIC32MX1XX/2XX

The MIPS architecture defines that the result of a

multiply or divide operation be placed in the HI and LO

registers. Using the Move-From-HI (MFHI) and Move-

From-LO (MFLO) instructions, these values can be

transferred to the General Purpose Register file.

In addition to the HI/LO targeted operations, the

MIPS32® architecture also defines a multiply instruc-

tion, MUL, which places the least significant results in

the primary register file instead of the HI/LO register

pair. By avoiding the explicit MFLO instruction required

when using the LO register, and by supporting multiple

destination registers, the throughput of multiply-inten-

sive operations is increased.

Two other instructions, Multiply-Add (MADD) and

Multiply-Subtract (MSUB), are used to perform the

multiply-accumulate and multiply-subtract operations.

The MADD instruction multiplies two numbers and then

adds the product to the current contents of the HI and

LO registers. Similarly, the MSUB instruction multiplies

two operands and then subtracts the product from the

HI and LO registers. The MADD and MSUB operations

are commonly used in DSP algorithms.

3.2.3 SYSTEM CONTROL

COPROCESSOR (CP0)

In the MIPS architecture, CP0 is responsible for the

virtual-to-physical address translation, the exception

control system, the processor’s diagnostics capability,

the operating modes (Kernel, User and Debug) and

whether interrupts are enabled or disabled. Configura-

tion information, such as presence of options like

MIPS16e, is also available by accessing the CP0

registers, listed in Tab l e 3 - 2.

Coprocessor 0 also contains the logic for identifying

and managing exceptions. Exceptions can be caused

by a variety of sources, including alignment errors in

data, external events or program errors. Table 3-3 lists

the exception types in order of priority.

TABLE 3-3: MIPS32® M4K® PROCESSOR CORE EXCEPTION TYPES

3.3 Power Management

The MIPS® M4K® processor core offers a number of

power management features, including low-power

design, active power management and power-down

modes of operation. The core is a static design that

supports slowing or Halting the clocks, which reduces

system power consumption during Idle periods.

3.3.1 INSTRUCTION-CONTROLLED

POWER MANAGEMENT

The mechanism for invoking Power-Down mode is

through execution of the WAIT instruction. For more

information on power management, see Section 25.0

“Power-Saving Features”.

3.4 EJTAG Debug Support

The MIPS® M4K® processor core provides for an

Enhanced JTAG (EJTAG) interface for use in the soft-

ware debug of application and kernel code. In addition

to standard User mode and Kernel modes of operation,

the M4K® core provides a Debug mode that is entered

after a debug exception (derived from a hardware

breakpoint, single-step exception, etc.) is taken and

continues until a Debug Exception Return (DERET)

instruction is executed. During this time, the processor

executes the debug exception handler routine.

The EJTAG interface operates through the Test Access

Port (TAP), a serial communication port used for trans-

ferring test data in and out of the core. In addition to the

standard JTAG instructions, special instructions

defined in the EJTAG specification define which

registers are selected and how they are used.

4.0 MEMORY ORGANIZATION

PIC32MX1XX/2XX microcontrollers provide 4 GB of

unified virtual memory address space. All memory

regions, including program, data memory, SFRs and

Configuration registers, reside in this address space at

their respective unique addresses. The program and

data memories can be optionally partitioned into user

and kernel memories. In addition, the data memory can

be made executable, allowing PIC32MX1XX/2XX

devices to execute from data memory.

Key features include:

• 32-bit native data width

• Separate User (KUSEG) and Kernel

(KSEG0/KSEG1) mode address space

• Flexible program Flash memory partitioning

• Flexible data RAM partitioning for data and

program space

• Separate boot Flash memory for protected code

• Robust bus exception handling to intercept

runaway code

• Simple memory mapping with Fixed Mapping

Translation (FMT) unit

• Cacheable (KSEG0) and non-cacheable (KSEG1)

address regions

4.1 PIC32MX1XX/2XX Memory Layout

PIC32MX1XX/2XX microcontrollers implement two

address schemes: virtual and physical. All hardware

resources, such as program memory, data memory

and peripherals, are located at their respective physical

addresses. Virtual addresses are exclusively used by

the CPU to fetch and execute instructions as well as

access peripherals. Physical addresses are used by

bus master peripherals, such as DMA and the Flash

controller, that access memory independently of the

CPU.

The memory maps for the PIC32MX1XX/2XX devices

are illustrated in Figure 4-1 and Figure 4-2.

Note: This data sheet summarizes the features

of the PIC32MX1XX/2XX family of

5.0 FLASH PROGRAM MEMORY

PIC32MX1XX/2XX devices contain an internal Flash

program memory for executing user code. There are

three methods by which the user can program this

memory:

• Run-Time Self-Programming (RTSP)

• EJTAG Programming

• In-Circuit Serial Programming™ (ICSP™)

RTSP is performed by software executing from either

Flash or RAM memory. Information about RTSP

techniques is available in Sec tion 5. “Flash Pro gram

Memory” (DS61121) in the “PIC32 Family Reference

Manual”.

EJTAG is performed using the EJTAG port of the

device and an EJTAG capable programmer.

ICSP is performed using a serial data connection to the

device and allows much faster programming times than

RTSP.

The EJTAG and ICSP methods are described in the

“PIC32 Flash Programming Specification” (DS61145),

which can be downloaded from the Microchip web site.

Note 1: This data sheet summarizes the features

of the PIC32MX1XX/2XX family of

devices. It is not intended to be a

comprehensive reference source. To

complement the information in this data

sheet, refer to Section 5. “Flash

Program Memory” (DS61121) in the

“PIC32 Family Reference Manual”, which

is available from the Microchip web site

(www.microchip.com/PIC32).

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 Flash page size on

PIC32MX1XX/2XX devices is 1 KB and

the row size is 128 bytes (256 IW and 32

IW, respectively).

7.0 INTERRUPT CONTROLLER

PIC32MX1XX/2XX devices generate interrupt requests

in response to interrupt events from peripheral modules.

The interrupt control module exists externally to the CPU

logic and prioritizes the interrupt events before

presenting them to the CPU.

The PIC32MX1XX/2XX interrupt module includes the

following features:

• Up to 64 interrupt sources

• Up to 44 interrupt vectors

• Single and multi-vector mode operations

• Five external interrupts with edge polarity control

• Interrupt proximity timer

• Seven user-selectable priority levels for each

vector

• Four user-selectable subpriority levels within each

priority

• Software can generate any interrupt

• User-configurable interrupt vector table location

• User-configurable interrupt vector spacing

9.0 DIRECT MEMORY ACCESS

(DMA) CONTROLLER

The PIC32 Direct Memory Access (DMA) controller is a

bus master module useful for data transfers between

different devices without CPU intervention. The source

and destination of a DMA transfer can be any of the

memory mapped modules existent in the PIC32 (such

as Peripheral Bus (PBUS) devices: SPI, UART, PMP,

etc.) or memory itself.

Following are some of the key features of the DMA

controller module:

• Four identical channels, each featuring:

- Auto-increment source and destination

address registers

- Source and destination pointers

- Memory to memory and memory to

peripheral transfers

• Automatic word-size detection:

- Transfer granularity, down to byte level

- Bytes need not be word-aligned at source

and destination

• Fixed priority channel arbitration

• Flexible DMA channel operating modes:

- Manual (software) or automatic (interrupt)

DMA requests

- One-Shot or Auto-Repeat Block Transfer

modes

- Channel-to-channel chaining

• Flexible DMA requests:

- A DMA request can be selected from any of

the peripheral interrupt sources

- Each channel can select any (appropriate)

observable interrupt as its DMA request

source

- A DMA transfer abort can be selected from

any of the peripheral interrupt sources

- Pattern (data) match transfer termination

• Multiple DMA channel status interrupts:

- DMA channel block transfer complete

- Source empty or half empty

- Destination full or half full

- DMA transfer aborted due to an external

event

- Invalid DMA address generated

• DMA debug support features:

- Most recent address accessed by a DMA

channel

- Most recent DMA channel to transfer data

• CRC Generation module:

- CRC module can be assigned to any of the

available channels

- CRC module is highly configurable

bit 31-0 DCRCDATA<31:0>: CRC Data Register bits

Writing to this register will seed the CRC generator. Reading from this register will return the current value of

the CRC. Bits greater than PLEN will return ‘0’ on any read.

When CRCTYP (DCRCCON<15>) = 1 (CRC module is in IP Header mode):

Only the lower 16 bits contain IP header checksum information. The upper 16 bits are always ‘0’. Data written

to this register is converted and read back in 1’s complement form (i.e., current IP header checksum value).

When CRCTYP (DCRCCON<15>) = 0 (CRC module is in LFSR mode):

Bits greater than PLEN will return ‘0’ on any read.

10.0 USB ON-THE-GO (OTG)

The Universal Serial Bus (USB) module contains

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. This module in Host mode is

intended for use as an embedded host and therefore

does not implement a UHCI or OHCI controller.

The USB module consists of the clock generator, the

USB voltage comparators, the transceiver, the Serial

Interface Engine (SIE), a dedicated USB DMA control-

ler, pull-up and pull-down resistors, and the register

interface. A block diagram of the PIC32 USB OTG

module is presented in Figure 10-1.

The clock generator provides the 48 MHz clock

required for USB full-speed and low-speed communi-

cation. 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 hardware protocol for data

transfers. The USB DMA controller transfers data

between the data buffers in RAM and the SIE. The inte-

grated 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.

The PIC32 USB module includes the following

features:

• USB Full-speed support for host and device

• Low-speed host support

• USB OTG support

• Integrated signaling resistors

• Integrated analog comparators for VBUS

monitoring

• Integrated USB transceiver

• Transaction handshaking performed by hardware

• Endpoint buffering anywhere in system RAM

• Integrated DMA to access system RAM and Flash

Note 1: This data sheet summarizes the features

of the PIC32MX1XX/2XX family of

11.0 I/O PORTS General purpose I/O pins are the simplest of peripher-

als. They allow the PIC® MCU to monitor and control

other devices. To add flexibility and functionality, some

pins are multiplexed with alternate function(s). These

functions depend on which peripheral features are on

the device. In general, when a peripheral is functioning,

that pin may not be used as a general purpose I/O pin.

Following are some of the key features of this module:

• Individual output pin open-drain enable/disable

• Individual input pin weak pull-up and pull-down

• Monitor selective inputs and generate interrupt

when change in pin state is detected

• Operation during CPU Sleep and Idle modes

• Fast bit manipulation using CLR, SET and INV

registers

Figure 11-1 illustrates a block diagram of a typical

multiplexed I/O port.

11.1 Parallel I/O (PIO) Ports

All port pins have ten registers directly associated with

their operation as digital I/O. The data direction register

(TRISx) determines whether the pin is an input or an

output. If the data direction bit is a ‘1’, then the pin is an

input. All port pins are defined as inputs after a Reset.

Reads from the latch (LATx) read the latch. Writes to

the latch write the latch. Reads from the port (PORTx)

read the port pins, while writes to the port pins write the

latch.

11.1.1 OPEN-DRAIN CONFIGURATION

In addition to the PORTx, LATx, and TRISx 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 con-

figures the corresponding pin to act as an open-drain

output.

The open-drain feature allows the generation of out-

puts higher than VDD (e.g., 5V) on any desired 5V-tol-

erant pins by using external pull-up resistors. The

maximum open-drain voltage allowed is the same as

the maximum VIH specification.

See the “Pin Diagrams” section for the available pins

and their functionality.

11.1.2 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.

11.1.3 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.

11.1.4 INPUT CHANGE NOTIFICATION

The input change notification function of the I/O ports

allows the PIC32MX1XX/2XX 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.

Five control registers are associated with the CN func-

tionality 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.

The CNSTATx register indicates whether a change

occurred on the corresponding pin since the last read

of the PORTx bit.

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.

An additional control register (CNCONx) is shown in

11.2 CLR, SET and INV Registers

Every I/O module register has a corresponding CLR

(clear), SET (set) and INV (invert) register designed to

provide fast atomic bit manipulations. As the name of

the register implies, a value written to a SET, CLR or

INV register effectively performs the implied operation,

but only on the corresponding base register and only

bits specified as ‘1’ are modified. Bits specified as ‘0’

are not modified.

Reading SET, CLR and INV registers returns undefined

values. To see the affects of a write operation to a SET,

CLR or INV register, the base register must be 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.

11.3 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 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.

11.3.1 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” in their full pin designation, where “RP”

designates a remappable peripheral and “n” is the

remappable port number.

11.3.2 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

among others. A similar requirement excludes all mod-

ules with analog inputs, such as the Analog-to-Digital

Converter (ADC).

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.

11.3.3 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.

11.3.4 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 [pin name]R registers, where [pin

name] refers to the peripheral pins listed in Table 11-1,

are used to configure peripheral input mapping (see

fields. Programming these bit fields with an appropriate

value maps the RPn pin with the corresponding value to

that peripheral. For any given device, the valid range of

values for any bit field is shown in Table 11-1.

For example, Figure 11-2 illustrates the remappable

pin selection for the U1RX input.

FIGURE 11-2: REMAPPABLE INPUT

EXAMPLE FOR U1RX

RPA2

RPB6

2U1RX input

to peripheral

RPn

Note: For input only, peripheral pin select functionality

does not have priority over TRISx settings.

Therefore, when configuring RPn pin for input,

the corresponding bit in the TRISx register must

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

11.3.5 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 RPnR registers (Register 11-2) are

used to control output mapping. Like the [pin name]R

registers, each register contains sets of 4 bit fields.

The value of the bit field corresponds to one of the

peripherals, and that peripheral’s output is mapped

to the pin (see Table 11-2 and Figure 11-3).

A null output is associated with the output register reset

value of ‘0’. This is done to ensure that remappable

outputs remain disconnected from all output pins by

default.

MULTIPLEXING OF

FOR RPA0

11.3.6 CONTROLLING CONFIGURATION

CHANGES

Because peripheral remapping can be changed during

run time, some restrictions on peripheral remapping

are needed to prevent accidental configuration

changes. PIC32 devices include two features to

prevent alterations to the peripheral map:

• Control register lock sequence

• Configuration bit select lock

11.3.6.1 Control Register Lock

Under normal operation, writes to the RPnR and [pin

name]R registers are not allowed. Attempted writes

appear to execute normally, but the contents of the

registers remain unchanged. To change these regis-

ters, they must be unlocked in hardware. The regis-

ter lock is controlled by the IOLOCK Configuration bit

(CFGCON<13>). Setting IOLOCK prevents writes to

the control registers; clearing IOLOCK allows writes.

To set or clear the IOLOCK bit, an unlock sequence

must be executed. Refer to Section 6. “Oscillator”

(DS61112) in the “PIC32 Family Reference Manual” for

details.

11.3.6.2 Configuration Bit Select Lock

As an additional level of safety, the device can be

configured to prevent more than one write session to

the RPnR and [pin name]R registers. The IOL1WAY

Configuration bit (DEVCFG3<29>) blocks the IOLOCK

bit from being cleared after it has been set once. If

IOLOCK remains set, the register unlock procedure

does not execute, and the peripheral pin select control

registers cannot be written to. The only way to clear the

bit and re-enable peripheral remapping is to perform a

device Reset.

In the default (unprogrammed) state, IOL1WAY is set,

restricting users to one write session.

14.0 INPUT CAPTURE

The Input Capture module is useful in applications

requiring frequency (period) and pulse measurement.

The Input Capture module captures the 16-bit or 32-bit

value of the selected Time Base registers when an

event occurs at the ICx pin. The following events cause

capture events:

• Simple capture event modes

- Capture timer value on every rising and falling

edge of input at ICx pin

• Capture timer value on every edge (rising and

falling)

• Capture timer value on every edge (rising and

falling), specified edge first.

• Prescaler capture event modes

- Capture timer value on every 4th rising edge of

input at ICx pin

- Capture timer value on every 16th rising edge of

input at ICx pin

Each input capture channel can select between one of

two 16-bit timers (Timer2 or Timer3) for the time base,

or two 16-bit timers (Timer2 and Timer3) together to

form a 32-bit timer. The selected timer can use either

an internal or external clock.

Other operational features include:

• Device wake-up from capture pin during CPU

Sleep and Idle modes

• Interrupt on input capture event

• 4-word FIFO buffer for capture values (interrupt

optionally generated after 1, 2, 3 or 4 buffer

locations are filled)

• Input capture can also be used to provide

additional sources of external interrupts

15.0 OUTPUT COMPARE The Output Compare module (OCMP) is used to gen-

erate a single pulse or a train of pulses in response to

selected time base events. For all modes of operation,

the OCMP module compares the values stored in the

OCxR and/or the OCxRS registers to the value in the

selected timer. When a match occurs, the OCMP

module generates an event based on the selected

mode of operation.

The following are some of the key features:

• Multiple Output Compare Modules in a device

• Programmable interrupt generation on compare

event

• Single and Dual Compare modes

• Single and continuous output pulse generation

• Pulse-Width Modulation (PWM) mode

• Hardware-based PWM Fault detection and

automatic output disable

• Programmable selection of 16-bit or 32-bit time

bases

• Can operate from either of two available 16-bit

time bases or a single 32-bit time base

17.0 INTER-INTEGRATED

CIRCUIT™ (I2C™) The I2C module provides complete hardware support

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

communication standard. Figure 17-1 illustrates the

I2C module block diagram.

Each I2C module has a 2-pin interface: the SCLx pin is

clock and the SDAx pin is data.

Each I2C module offers the following key features:

•I

2C interface supporting both master and slave

operation

•I

2C Slave mode supports 7-bit and 10-bit addressing

•I

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

addressing

•I

2C port allows bidirectional transfers between

master and slaves

• Serial clock synchronization for the 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

• Provides support for address bit masking

18.0 UNIVERSAL ASYNCHRONOUS

RECEIVER TRANSMITTER

(UART)

The UART module is one of the serial I/O modules

available in PIC32MX1XX/2XX family devices. The

UART is a full-duplex, asynchronous communication

channel that communicates with peripheral devices

and personal computers through protocols, such as

RS-232, RS-485, LIN and IrDA®. The module also sup-

ports the hardware flow control option, with UxCTS and

UxRTS pins, and also includes an IrDA encoder and

decoder.

The primary features of the UART module are:

• Full-duplex, 8-bit or 9-bit data transmission

• Even, Odd or No Parity options (for 8-bit data)

• One or two Stop bits

• Hardware auto-baud feature

• Hardware flow control option

• Fully integrated Baud Rate Generator (BRG) with

16-bit prescaler

• Baud rates ranging from 38 bps to 12.5 Mbps at

50 MHz

• 8-level deep First-In-First-Out (FIFO) transmit

data buffer

• 8-level deep FIFO receive data buffer

• Parity, framing and buffer overrun error detection

• Support for interrupt-only on address detect

(9th bit = 1)

• Separate transmit and receive interrupts

• Loopback mode for diagnostic support

• LIN Protocol support

• IrDA encoder and decoder with 16x baud clock

output for external IrDA encoder/decoder support

Figure 18-1 illustrates a simplified block diagram of the

UART.

bit 7-5 SSRC<2:0>: Conversion Trigger Source Select bits

111 = Internal counter ends sampling and starts conversion (auto convert)

110 = Reserved

101 = Reserved

100 = Reserved

011 = CTMU ends sampling and starts conversion

010 = Timer 3 period match ends sampling and starts conversion

001 = Active transition on INT0 pin ends sampling and starts conversion

000 = Clearing SAMP bit ends sampling and starts conversion

Note 1: When using 1:1 PBCLK divisor, the user’s software should not read/write the peripheral’s SFRs in the

SYSCLK cycle immediately following the instruction that clears the module’s ON bit.

2: If ASAM = 0, software can write a ‘1’ to start sampling. This bit is automatically set by hardware if

ASAM = 1. If SSRC = 0, software can write a ‘0’ to end sampling and start conversion. If SSRC ‘0’, this

bit is automatically cleared by hardware to end sampling and start conversion.

3: This bit is automatically set by hardware when analog-to-digital conversion is complete. Software can

write a ‘0’ to clear this bit (a write of ‘1’ is not allowed). Clearing this bit does not affect any operation

already in progress. This bit is automatically cleared by hardware at the start of a new conversion.

bit 4 CLRASAM: Stop Conversion Sequence bit (when the first ADC interrupt is generated)

1 = Stop conversions when the first ADC interrupt is generated. Hardware clears the ASAM bit when the

ADC interrupt is generated.

0 = Normal operation, buffer contents will be overwritten by the next conversion sequence

bit 3 Unimplemented: Read as ‘0’

bit 2 ASAM: ADC Sample Auto-Start bit

1 = Sampling begins immediately after last conversion completes; SAMP bit is automatically set.

0 = Sampling begins when SAMP bit is set

bit 1 SAMP: ADC Sample Enable bit(2)

1 = The ADC sample and hold amplifier is sampling

0 = The ADC sample/hold amplifier is holding

When ASAM = 0, writing ‘1’ to this bit starts sampling.

When SSRC = 000, writing ‘0’ to this bit will end sampling and start conversion.

bit 0 DONE: Analog-to-Digital Conversion Status bit(3)

1 = Analog-to-digital conversion is done

0 = Analog-to-digital conversion is not done or has not started

Clearing this bit will not affect any operation in progress.
