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.
Microchip received ISO/TS-16949:200 2 certif ication for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in Calif ornia
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microper ipher als, nonvol ati le memo ry and
analog product s. In addition, Microchip s quality system for th e design
and manufacture of development systems is ISO 9001:2000 certified.

2.0 GUIDELINES FOR GETTING
STARTED WITH 32-BIT
MICROCONTROLLERS
2.1 Basic Connection Requirements
Getting started with the PIC32MX3XX/4XX family of
32-bit Microcontrollers (MCUs) requires attention to a
minimal set of device pin connections before
proceeding with development. Th e following is a list of
pin names, which must always be connected:
All VDD and VSS pins
(see Section 2.2 “Decoupling Capacitors”)
All AVDD and AVSS pins (regardless if ADC module
is not used)
(see Section 2.2 “Decoupling Capacitors”)
•V
CAP/VCORE
(see Section 2.3 “Capacitor on Internal Voltage
Regulator (VCAP/VCORE)”)
•MCLR
pin
(see Section 2.4 “Master Clear (MCLR) Pin”)
PGECx/PGEDx pins used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes
(see Section 2.5 “ICSP Pins”)
OSC1 and OSC2 pins when external oscillator
source is used
(see Section 2.8 “External Oscillato r Pin s”)
Additionally, the following pins may be required:
•V
REF+/VREF- pins used when external voltage
reference for ADC module is implemented
2.2 Decoupling Capacitors
The use of decoupling capacitors on every pair of
power supply pins, such as VDD, VSS, AVDD and
AVSS is required. See Figure 2-1.
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 that ceramic capacitors be used.
Placement on the printed circuit board: The
decoupling capacitors should be placed as close
to the pins as possible. It is recommended to
place the capacitors on the same side of the
board as the device. If space is constricted, the
capacitor can be placed on another layer on the
PCB using a via; however, ensure that the trace
length from the pin to the capacitor is within
one-quarter inch (6 mm) in length.
Handling high 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 parallel 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-spe ed circuit designs, consider
implementing 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
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 PIC32MX3XX/4XX family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to 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 avail-
able 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 ADC use and
ADC voltage reference source.

2.2.1 BULK CAPACITORS
The use of a bulk capacitor is recommended to improve
power supply stability . T ypical values range from 4.7 µF
to 47 µF. This capacitor should be located as close to
the device as possible.
2.3 Capacitor on Internal Voltage
Regulator (VCAP/VCORE)
2.3.1 INTERNAL REGULATOR MODE
A low-ESR (< 1 Ohm) capacitor is required on the
VCAP/VCORE pin, which is use d to stabilize the internal
voltage regulator output. The VCAP/VCORE 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
“Electrical Characteristics” for additional information
on CEFC specifications. This mode is enabled by
connecting the ENVREG pin to VDD.
2.3.2 EXTERNA L REGULA TOR MODE
In this mode the core voltage is supplied externally
through the VCORE/VCAP pin. A low-ESR capacitor of
10 µF is recommended on the VCAP/VCORE pin. This
mode is enabled by grounding the ENVREG pin.
The placement of this capacitor should be close to th e
VCAP/VCORE. It is recommended that the trace length
not exceed one-quarter inch (6 mm). Refer to
Section 26.3 “On-Chip Voltage Regulator” for
details.
2.4 Master Clear (MCLR) Pin
The MCLR pin provides for two specific device
functions:
Devic e Re set
Device Programming and D ebugging
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 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 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/d ebugger commu ni-
cations to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternately, refe r to the AC/DC charac teri sti cs and tim-
ing 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 Ch annel Sele ct” (i.e .,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® ICD 2, MPLAB ICD 3 or MPLAB REAL ICE™.
For more information on ICD 2, ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip web
site.

Guide” DS51331

“MPLAB® REAL ICE™ In-Circuit Debugger
User’s Guide” DS51616
“Using MPLAB® REAL ICE™” (poster) DS51749
2.6 JTAG
The TMS, TDO, TDI and TCK pins are used for testing
and debugging according to the Joint Test Action
Group (JT AG) 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. Alternately , refer to the AC/DC characteris-
tics and timing requirements information in the respec-
tive device Flash programming specification for
information on capacitive loading limits and pin input
voltage high (VIH) and input low (VIL) requirements.
2.7 Trace
The trace pins can be conn ected to a hardware-trace-
enabled programmer to provide a compress real time
instruction trace. When used for trace the TRD3,
TRD2, TRD1, TRD0 and T RCLK pins should be dedi-
cated for this use. The trace hardware requires a 22
Ohm series resistor between the trace pins and the
trace connector.
2.8 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 circuit close to the respective oscillato r 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 illustrated in Figure 2-3.

2.9 Configuration of Analog and
Digital Pins During ICSP
Operations
If MPLAB ICD 2, ICD 3 or REAL ICE is sel ected as a
debugger, it automatically initializes all of the Analog-
to-Digital input pins (ANx) as “digital” pins by setting all
bits in the ADPCFG register.
The bits in this register that correspond to the Analog-
to-Digital pins that are initialized by MPLAB ICD 2, ICD
3 or REAL ICE, must not be cleared by the user
application firmware; o therwise, communication errors
will result between the debugger and the device.
If your application needs to use certain Analog-to-
Digital pins as analog input pins during the debug
session, the user application must clear the
corresponding bits in the ADPCFG register during
initialization of the ADC module.
When MPLAB ICD 2, ICD 3 or REAL ICE is used a s a
programmer, the user application firmware must
correctly configure the ADPCFG register. Automatic
initialization of this register is only done during
debugger operation. Failure to correctly configure the
register(s) will result in all Analog-to-Digital pins being
recognized as analog input pins, resulting in the port
value being read as a logic ‘0’, which may affect user
application functionality.
2.10 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.
Alternately, 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 Un it (MDU)
System Control Coprocessor (CP0)
Fixed Mapping Translation (FMT)
Dual Intern al Bus interfaces
Power Management
MIPS16e Support
Enhanced JTAG (EJTAG) Controll er
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 used for
integer operations and address calc ulation. One addi-
tional register file shadow set (containing thirty-two reg-
isters) is added to minimize context switching overhead
during interrupt/exception processi ng. 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 us ed 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 instructions 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 /DIV IDE UNIT (MDU)
The MIPS32® M4K® Processor Core incl udes 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) repres ents the rs operand. The second
number (‘16’ of 32x16) represents the rt operan d. The
PIC32MX core only checks the value of the latter (rt)
operand 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 automa tically determined
by logic built into the MDU.
Divide operations are impl emented 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 subsequent 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 reissu ed) and late ncy (num-
ber of cycles until a result is available) for the PIC32MX
core multiply and divide instructions. The approximate
latency and repeat rates are listed in terms of pipeline
clocks.

PIC32MX3XX/4XX
The MIPS architecture defines that the resu lt of a mul-
tiply or divide operation be placed in the HI and LO reg-
isters. Using the Move-From-HI (MFHI) and Move-
From-LO (MFLO) instructions, these values can be
transferr ed to th e g en e r a l purp ose register fil e.
In addition to the HI/LO targeted operations, the
MIPS32 architecture also defines a multiply instruction,
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-intensive operations is increased.
Two other instructions, multiply-add (MADD) and multi-
ply-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 vir-
tual-to-physical address translation, the exception con-
trol system, the processor ’s diagnostics capability, the
operating modes (kernel, user and debug), and
whether interrupts are enabled or disabled. Config ura-
tion information, such as presence of options like
MIPS16e, is also available by accessing the CP0
registers, listed in Table 3-2.

3.3 Power Management
The MIPS32® 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”.
3.3.2 LOCAL CLOCK GATING
The majority of the power consumed by the
PIC32MX3XX/4XX family core is in the clock tree and
clocking registers. The PIC32MX family uses extensive
use of local gated-clocks to reduce this dynamic power
consumption.
3.4 EJTAG Debug Support
The MIPS32® M4K® Processor Core provides for an
Enhanced JTAG (EJTAG) interface for use in the
software debug of application and kernel code. In
addition to standard user mode and kernel modes of
operation, the 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 EJT AG interface operates through the Test Access
Port (TAP), a serial communication port used for
transferring test data in and out of the core. In addition
to the standard JTAG instructions, special instructions
defined in the EJTAG specification define what
registers are selected and how they are used.

4.0 MEMORY ORGANIZATION
PIC32MX3XX/4XX microcontrollers provide 4 GB of
unified virtual memory address space. All memory
regions including program, data memory, SFRs and
Configuration registers reside in this addre ss 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 PIC32MX3XX/4XX to
execute from data memory.
4.1 Key Features
32-bit native data width
Separate User and Kernel 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 and non-cacheable address regions
4.2 PIC32MX3XX/4XX Memory Layout
PIC32MX3XX/4XX microcontrollers implement two
address spaces: 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
peripherals such as DMA and Flash controller that
access memory independently of CPU.

5.0 FLASH PROGRAM MEMORY
PIC32MX3XX/4XX devices contain an internal
program Flash memory for executing user code. There
are three methods by which the user can program this
memory:
Run-Time Self Programming (RTSP)
In-Circuit Serial Programming™ (ICSP™)
EJTAG Programming
RTSP is performed by software executing from either
Flash or RAM memory. EJTAG is p erformed using the
EJTAG port of the device and a EJTAG capable
programmer. ICSP is performed using a serial data
connection to the device and allows much faster pro-
gramming times than RTSP. RTSP techniques are
described in this chapter. The ICSP and EJTAG
methods are described in the “PIC32MX Flash
Programming Specification” (DS61145), which can be
downloaded from the Microchip web site.

Note 1: This data sheet summarizes the features
of the PIC32MX3XX/4XX family of
devices. It is not intended to be a compre-
hensive reference source. To comple-

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: Flash LVD Delay (LVDstartup) must be
taken into account between setting up and
executing any Flash comma nd operation.
See Example 5-1 for a code example to
set up and execute a Flash command
operation.
NVMCON = 0x4004; // Enable and configure for erase operation
Wait(delay); // Delay for 6 µs for LVDstartup

NVMKEY = 0x556699AA;
NVMCONSET = 0x8000; // Initiate operation

10.0 DIRECT MEMORY ACCESS
(DMA) CONTROLLER
The PIC32MX 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
PIC32MX (such as Peripheral Bus (PBUS) devices:
SPI, UART, PMP, and so on) or memory itself.
Following are some of the key features of the DMA
controller module:
Four Identical Channels, each featuri ng:
- Auto-Increment Source and Destination
Address Registers
- Source and Destinatio n 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 Mode s:
- Manual (software) or automatic (interrupt)
DMA requests
- One-Shot or Auto-Repeat Block Transfer
modes
- Channe l-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 (d ata) 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:

11.0 USB ON-THE-GO (OTG)
The Universal Serial Bus (USB) module co ntains ana-
log 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 PIC3 2MX USB OTG
module is presented in Figure 11-1.
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 PIC32MX 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

12.0 I/O PORTS General purpose I/O pins a re the simpl est of peripher-
als. They allow the PIC® MCU to monitor and control
other devices. To add flexibility and fu nctionality, 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 feat ures of this modu l e:
Individual Output Pin Open-drain Enable/Disable
Individual Input Pin Weak Pull-up Enable/Disable
Monitor Sel ective 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 12-1 illustrates a block diagram of a typical
multiplexed I/O port.

12.1 Parallel I/O (PIO) Ports
All port pins have three registers (TRIS, LAT and
PORT) that are directly associated with their operation.
TRIS is a data direction or tri-state control register that
determines whether a digital pin is an input or an out-
put. Setting a TRISx register bit = 1 configures the cor-
responding I/O pin as an input; setting a TRISx register
bit = 0 configures the corre spond ing I/O pi n a s an out-
put. All port I/O pins are defined as inputs after a device
Reset. Certain I/O pins are shared with analog
peripherals and default to analog inputs after a device
Reset.
PORT is a register used to read the current state of the
signal applied to the port I/O pins. Writing to a PORTx
register performs a write to the port’s latch, LATx
register, latching the data to the port’s I/O pins.
LAT is a register used to write data to the port I/O pins.
The LATx l atch reg ister holds th e d ata written to eith er
the LATx or PORTx registers. Reading the LATx latch
register reads the last value written to the
corresponding port or latch register.
Not all port I/O pins are implemented on some devices,
therefore, the corresponding PORTx, LATx and TRISx
register bits will read as zeros.
12.1.1 CLR, SET AND INV REGISTERS
Every I/O module register has a corresponding CLR
(clear), SET (set) and INV (invert) register de si gned 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.
12.1.2 DIGITAL INPUTS
Pins are configured a s digital inputs by setting the cor-
responding TRIS register bits = 1. When configured as
inputs, they are either TTL buffers or Schmitt Triggers.
Several digital pins share functionality with analog
inputs and default to the analog inputs at POR. Setting
the corresponding bit in the AD1PCFG register = 1
enables the pin as a digital pin.
The maximum input voltage allowed on the input pins
is the same as the maximum V IH specification. Refer to
Section 29.0 “Electrical Characteristics” for VIH
specification details.
12.1.3 ANALOG INPUTS
Certain pins can be configured as analog inputs used
by the ADC and Comparator modules. Setting the cor-
responding bits in the AD1PCFG regi ster = 0 enables
the pin as an analog input pin and must have the corre-
sponding TRIS bit set = 1 (input). If the TRIS bit is
cleared = 0 (output), the digital output level (VOH or
VOL) will be converted. Any time a port I/O pin is config-
ured as analog, its digital input is disabled and the cor-
responding PORTx register bit will read ‘0’. The
AD1PCFG Register has a default value of 0x0000;
therefore, all pins that share ANx functions are anal og
(not digital) by default.
12.1.4 DIGITAL OUTPUTS
Pins are configured as digital outputs by setting the cor-
responding T RIS re gist er bits = 0. When configured as
digital outputs, these pins are CMOS drivers or can be
configured as open drain outputs by setting the corre-
sponding bits in the ODCx Open-Drain Configuration
register.
The open-drain feature allows the generation of
outputs higher than VDD (e.g., 5V) on any desired 5V
tolerant pins by using external pull-up resistors. The
maximum open-drain voltage allowed is the same as
the maximum VIH specification.
See the Pin Diagrams section for the available pins
and their functionality.
12.1.5 ANALOG OUTPUTS
Certain pins can be configured as analog outputs, such
as the CVREF output voltage used by the comparator
module. Configuring the Comparator Reference mod-
ule to provide this output will present the analog output
voltage on the pin, independent of the TRIS register
setting for the corresponding pin.
12.1.6 INPUT CHANGE NOTIFICATION
The input change notification function of the I/O ports
(CNx) allows devices to generate interrupt requ ests in
response to change of state on selected pin.
Each CNx pin also has a weak pull-up, which acts as a
current source connected to the pin. The pull-ups are
enabled by setting corresponding bit in CNPUE registe r .
Note: Using a PORTxINV register to toggle a bit
is recommended because the operation is
performed in hardware atomically, using
fewer instructions as compared to the tra-
ditional read-modify-write method shown
below:
PORTC ^= 0x0001;
Note: Analog levels on any pin that is defined as
a digital input (including the ANx pins)
may cause the input buffer to consume
current that exceeds the de v i ce specifica-
tions.

15.0 INPUT CAPTURE
The Input Capture module is useful in applications
requiring frequency (period) and pulse measurement.
The PIC32MX3XX/4XX devices support up to five input
capture channels.
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 events that cause a
capture event are listed below in three categories:
1. Simple Capture Event modes
- Capture timer value on every falling edge of
input at ICx pin
- Capture timer value on every rising edge of
input at ICx pin
2. Capture timer value on every edge (rising and
falling)
3. Capture timer value on every edge (rising and
falling), specified edge first.
4. Prescaler Capture Event modes
- Captu re 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 interrup ts

16.0 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 tim er. When a match occurs, the OC MP mod-
ule 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 outpu t 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

22.0 10-BIT ANALOG-TO-DIGITAL
CONVERTER (ADC)
The PIC32MX3XX/4XX 10-bit Analog-to-Digital
Converter (ADC) includes the following features:
Successive Approximation Register (SAR)
conversion
Up to 1000 kilo samples per second (ksps)
conversion speed
Up to 16 analog input pins
External voltage reference input pins
One unipolar, differential Sample-and-Hold
Amplifier (SHA)
Automatic Channel Scan mode
Selectable conversion trigger source
16-word conversion result buffer
Selectable Buffer Fill modes
Eight conversion result format options
Operation during CPU Sleep and Idle modes
A block diagram of the 10-bit ADC is illustrated in
Figure 22-1. The 10-bit ADC has 1 6 an alog inp ut pin s,
designated AN0-AN15 . In addition, there are two ana-
log input pins for external voltage reference connec-
tions. These voltage reference inputs may be shared
with other analog input pins and may be common to
other analog module references.
The analog inputs are connected through two multi-
plexers (MUXs) to one SHA. The analog input MUXs
can be switched between two sets of analog inputs
between conversions. Unipolar differential conversions
are possible on all channels, other than the pin used as
the reference, using a reference input pin (see
Figure 22-1).
The Analog Input Scan mode sequentially converts
user-specified channels. A control register specifies
which analog input channels will be included in the
scanning sequence.
The 10-bit ADC is connected to a 16-word result buffer .
Each 10-bit result is converted to one of eight, 32-bit
output formats when it is read from the result buffer.

24.0 COMPARATOR VOLTAGE
REFERENCE (CVREF)The CVREF is a 16-t ap, resistor ladder network that pro-
vides a selectable reference voltage. Although its pri-
mary purpose is to provide a reference for the analog
comparators, it also may be used independently of
them.
A block diagram of the module is illustrated in
Figure 24-1. The resistor ladder is segmented to
provide two ranges of voltage reference values and has
a power-down function to conserve power when the
reference is not being used. The module’s supply refer-
ence can be provided from either device VDD/VSS or an
external voltage reference. The CVREF output is avail-
able for the co mparators and typically available for pin
output.
The comparator voltage reference has the following
features:
High and low range selection
Sixteen output levels available for each range
Internally connected to comparators to conserve
device pins
Output can be connected to a pin

25.0 POWER-SAVING FEATURES
This section describes power-saving for the
PIC32MX3XX/4XX. The PIC32MX devices offer a total
of nine methods and modes that are organized into two
categories that allow the user to balance power con-
sumption with device performance. In all of the meth-
ods and modes described in this section, power-saving
is controlled by software.
25.1 Power-Saving with CPU Running
When the CPU is running, po wer consumption can be
controlled by reducing the CPU clock frequency , lower-
ing the PBCLK, and by individually disabling modules.
These methods are grouped into the following modes:
FRC Run mode: the CPU is clocked from the FRC
clock source with or without postscalers.
LPRC Run mode: the CPU is clocked from the
LPRC clock source.
•S
OSC Run mode: the CPU is clo cke d fro m th e
SOSC clock source.
Peripheral Bus Scaling mode: peripherals are
clocked at programmable fraction of the CPU
clock (SYSCLK).
25.2 CPU Halted Methods
The device supports two power-saving modes, Sleep
and Idle, both of which halt the clock to the CPU. These
modes operate with all clock sources, as listed below:
•P
OSC Idle Mode: the system clock is derived from
the POSC. The system clock source continues to
operate.
Peripherals continue to operate, but can
optionally be individually disabled.
FRC Idle Mode: the system clock is derived from
the FRC with or without postscalers. Peripherals
continue to operate, but can optionally be
individually disabled.
•S
OSC Idle Mode: the system clock is derived from
the SOSC. Peripherals continue to operate, but
can optionally be individua lly disabled.
LPRC Idle Mode: the system clock is derived from
the LPRC.
Peripherals continue to operate, but can option-
ally be individually disabled . This is the lowest
power mode for the device with a clock runnin g.
Sleep Mode: the CPU, the system clock source,
and any peripherals that operate from the system
clock source, are halted.
Some peripherals can operate in Sleep using spe-
cific clock sources. This is the lowest power mode
for the device.
25.3 Power-Saving Operation
The purpose of all power-saving is to reduce power
consumption by reducing the device clock frequency.
To achieve this, low-frequency clock sources can be
selected. In ad dition, the periphera ls and CPU can be
halted or disabled to further reduce power
consumption.
25.3.1 SLEEP MODE
Sleep mode has the lowest power consumption of the
device Power-Saving operating modes. The CPU and
most peripherals are halted. Select peripherals can
continue to operate in Sleep mode and can be used to
wake the device from Sleep. See the individual periph-
eral module sections for descriptions of behavior in
Sleep mode.
Sleep mode includes the following characteristics:
The CPU is halted.
The system clock source is typically shut down.
See Section 25.3.2 “Idle Mode” for specific
information.
There can be a wake-up delay based on the
oscillator selection.
The Fail-Safe Clock Monitor (FSCM) does not
operate during Sleep mode.
The BOR circuit, if enabled, remains operative
during Sleep mo de.
The WDT, if enabled, is not au tomatically cleared
prior to entering Sleep mode.
Some peripherals can continue to operate in
Sleep mode. These perip herals include I/O pins
that detect a change in the input signal, WDT,
ADC, UART and peripherals that use an external
clock input or the internal LPRC oscillator, e.g.,
RTCC and Timer 1.
I/O pins conti n ue to sink or source current in the
same manner as they do when the device is not in
Sleep.
The USB module can override the disabling of the
POSC or FRC. Refer to Section 11.0 “USB On-
The-Go (OTG)” for specific details.
Some modules can be individually disabled by
software prior to entering Sleep in order to further
reduce consumption.

of the PIC32MX3XX/4XX family 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 10. “Power-Saving
Features” (DS61130) of the “PIC32
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com/PIC32).

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.
PIC32MX3XX/4XX
DS61143H-page 130 © 2011 Microchip Technology Inc.
The processor will exit, or ‘wake-up’, from Sleep on one
of the following events:
On any interrupt from an enabled source that is
operating in Sleep. The interrupt priority must be
greater than the current CPU priority.
On any form of device Reset.
On a WDT time-o u t. Se e Section 26.2 “Watchdog
Timer (WDT)”.
If the interrupt priority is lower than or eq ual to current
priority, the CPU will remain halted, but the PBCLK will
start running and the device will enter into Idle mode.
25.3.2 IDLE MODE
In the Idle mode, the CPU is halted but the System
clock (SYSCLK) source is still enabled. This allows
peripherals to continue operation when the CPU is
halted. Peripherals can be individually configured to
halt when entering Idle by setting their respective SIDL
bit. Latency when exiting Idle mode is very low due to
the CPU oscillator source remaining active.
The device enters Idle mode when the SLPEN
(OSCCON<4>) bit is clear and a WAIT instruction is
executed.
The processor will wake or exit from Idle mode on the
following events:
On any interrupt event for which the interrupt
source is enabled. The priority of the interrupt
event must be greater than th e current priority of
CPU. If the priority of the interrupt event is lower
than or equal to current priority of CPU, the CPU
will remain halted and the device will remain in
Idle mode.
On any source of device Reset.
On a WDT time-out interrupt. See Section 26.2
“Watchdog Timer (WDT)”.
25.3.3 PERIPHERAL BUS SCALING
METHOD
Most of the peripherals on the device are clocked using
the PBCLK. The periphera l bus can be scaled rel ative
to the SYSCLK to minimize the dynamic power con-
sumed by the peripherals. The PBCLK divisor is con-
trolled by PBDIV<1:0> (OSCCON<20:19>), allowing
SYSCLK-to-PBCLK ratios of 1:1, 1:2, 1:4 and 1:8. All
peripherals using PBCLK are affected when the divisor
is changed. Peripherals such as USB, Interrupt Con-
troller, DMA, Bus Matrix and Prefetch Cache are
clocked directly from SYSCLK, as a result, they are not
affected by PBCLK divisor changes
Changing the PBCLK divisor affects:
The CPU to peripheral access latency. The CPU
has to wait for next PBCLK edge for a read to
complete. In 1:8 mode this results in a latency of
one to seven SYSCLKs.
The power consumption of the peripherals. Power
consumption is directly proportional to the fre-
quency at which the peripherals are clocked. The
greater the divisor , the lower the power consumed
by the peripherals.
To minimize dynamic power the PB divisor should be
chosen to run the peripherals at the lowest frequency
that provides acceptable system performance. When
selecting a PBCLK divider, peripheral clock require-
ments such as baud rate accuracy should be taken into
account. For example, the UART peripheral may not be
able to achieve all baud rate values at some PBCLK
divider depending on the SYSCLK value.
Note: There is no FRZ mode for this module.
Note: Changing the PBCLK divider ratio
requires recalculation of peripheral timing.
For example, assume the UART is config-
ured for 9600 baud with a PB clock ratio of
1:1 and a POSC of 8 MHz. When the PB
clock divisor of 1:2 is used, the input fre-
quency to the baud clock is cut in half;
therefore, the baud rate is reduced to 1/2
its former value. Due to numeric truncation
in calculations (such as the baud rate divi-
sor), the actual baud rate may be a tiny
percentage different than expected. For
this reason, any timing calculation
required for a peripheral should be per-
formed with the new PB clock frequency
instead of scaling the previous value
based on a change in PB divisor ratio.
Oscillator start-up and PLL lock delays are
applied when switching to a clock source
that was disabled and that uses a crystal
and/or the PLL. For example, assume the
clock source is switched from POSC to
LPRC just prior to entering Sleep in order to
save power. No oscillator start-up delay
would be applied when exiting Idle. How-
ever, when switching back to POSC, the
appropriate PLL and/or oscillator
startup/lock dela ys would be applied .

26.2 Watchdog Timer (WDT)
This section describes the operation of the WDT and
Power-Up Timer of the PIC32MX3XX/4XX.
The WDT, when enabled, operates from the internal
Low-Power Oscillator (LPRC) clock source and can be
used to detect system software malfunctions by reset-
ting the device if the WDT is not cle ared p eriodically in
software. Various WDT time-out periods can be
selected using the WDT postscaler. The WDT can also
be used to wake the device from Sleep or Idle mode.
The following are some of the key features of the WDT
module:
Configuration or software controlled
User-configurable time-out period
Can wake the device from Sleep or Idle

26.3 On-Chip Voltage Regulator
All PIC32MX3XX/4XX device’s core and digital logic
are designed to op erate at a nominal 1.8V. To simplify
system designs, most devices in the
PIC32MX3XX/4XX incorporate an on-chip regulator
providing the required core logic voltage from VDD.
The internal 1.8V regulator is controlled by the
ENVREG pin. Tying this pin to VDD enables the regu-
lator, which in turn provides power to the core. A low
ESR capacitor (such as tantalum) must be connected
to the VCORE/VCAP pin (Figure 26-2). This helps to
maintain the stability of the regulator. The recom-
mended value for the filer capacitor is provided in
Section 29.1 “DC Characteristics”.
T ying the ENVREG pin to VSS disables the re gulator . In
this case, separate power for the core logi c at a nomi-
nal 1.8V must be supplied to the device on the
VCORE/VCAP pin.
Alternatively , the VCORE/VCAP and VDD pins can be tied
together to operate at a lower nominal voltage. Refer to
Figure 26-2 for possible configurations.
26.3.1 ON-CHIP REGULA TOR AND POR
When the voltage regulator is enabled, it takes fixed
delay for it to generate output. During this time, desig-
nated as TPU, code execution is disabled. TPU is applied
every time the device resumes operation after any
power-down, including Sleep mode.
If the regulator is disabled, a separate Power-up Timer
(PWRT) is automatically enabled. The PWRT adds a
fixed delay of TPWRT at device start-up. See
Section 29.0 “Electrical Characteristics” for more
information on TPU AND TPWRT.
26.3.2 ON-CHIP REGULA TOR AND BOR
When the on-chip regulator is enabled,
PIC32MX3XX/4XX devices also have a simp le brown-
out capability. If the voltage suppl ied to the regulator is
inadequate to maintain a regulated level, the regu lator
Reset circuitry will generate a Brown-out Reset. This
event is captured by the BOR flag bit (RCON<1>). The
brown-out voltage levels are specific in Section 29.1
“DC Characteristics”.
26.3.3 POWER-UP REQUIREMENTS
The on-chip regulator is designed to meet the power-up
requirements for the device. If the application does not
use the regulator, then strict power-up conditions must
be adhered to. While powering up, VCORE must never
exceed VDD by 0.3 volts.

is placed as close as possible to the
