15.0 OUTPUT COMPARE
Note 1: This data sheet summarizes the features
of the PIC24HJXXXGPX06A/X08A/X10A
families of devices. It is not intended to be
a comprehensive reference source. To
complement the information in this data
sheet, refer to the “dsPIC33F/PIC24H
Family Reference Manual”, Section 13.
“Output Compare” (DS70247), which is
available on the Microchip web site
(www.microchip.com).
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.
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
