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

16.0 OUTPUT COMPARE

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 16. “Output

Compare” (DS60001111) in the “PIC32

Family Reference Manual”, which is

available from the Microchip web site

(www.microchip.com/PIC32).

The Output Compare module is used to generate a

single pulse or a train of pulses in response to selected

time base events. For all modes of operation, the

Output Compare 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 Output

Compare module generates an event based on the

selected mode of operation.

The following are the key features of this module:

• 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

• Can operate from either of two available 16-bit

time bases or a single 32-bit time base
