PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY

13.0 TIMER2/3, TIMER4/5

Note:

This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 14. “Timers”

(DS60001105) of the “PIC32 Family

Reference Manual”, which is available

from the Microchip web site

(www.microchip.com/PIC32).

This family of PIC32 devices features four synchronous

16-bit timers (default) that can operate as a free-

running interval timer for various timing applications

and counting external events. The following modes are

supported:

• Synchronous internal 16-bit timer

• Synchronous internal 16-bit gated timer

• Synchronous external 16-bit timer

Two 32-bit synchronous timers are available by

combining Timer2 with Timer3 and Timer4 with Timer5.

The 32-bit timers can operate in three modes:

• Synchronous internal 32-bit timer

• Synchronous internal 32-bit gated timer

• Synchronous external 32-bit timer

Note:

In this chapter, references to registers,

TxCON, TMRx and PRx, use ‘x’ to

represent Timer2 through 5 in 16-bit

modes. In 32-bit modes, ‘x’ represents

Timer2 or 4; ‘y’ represents Timer3 or 5.

13.1 Additional Supported Features

• Selectable clock prescaler

• Timers operational during CPU idle

• Time base for Input Capture and Output Compare

modules (Timer2 and Timer3 only)

• ADC event trigger (Timer3 in 16-bit mode, Timer2/

3 in 32-bit mode)

• Fast bit manipulation using CLR, SET and INV

registers
