15.0 OUTPUT COMPARE

Note:

This data sheet summarizes the features

of the dsPIC33FJXXXGPX06/X08/X10

families of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 13. “Output

Compare” (DS70209) in the “dsPIC33F

Family Reference Manual”,, which is avail-

able on the Microchip web site

(www.microchip.com).

The output compare module can select either Timer2 or

Timer3 for its time base. The module compares the

value of the timer with the value of one or two Compare

registers depending on the operating mode selected.

The state of the output pin changes when the timer

value matches the Compare register value. The output

compare module generates either a single output

pulse, or a sequence of output pulses, by changing the

state of the output pin on the compare match events.

The output compare module can also generate

interrupts on compare match events.

The output compare module has multiple operating

modes:

• Active-Low One-Shot mode

• Active-High One-Shot mode

• Toggle mode

• Delayed One-Shot mode

• Continuous Pulse mode

• PWM mode without Fault Protection

• PWM mode with Fault Protection
