PIC24HJ32GP302/304, PIC24HJ64GPX02/X04 AND PIC24HJ128GPX02/X04
15.0 OUTPUT COMPARE
Note 1: This data sheet summarizes the features
of
the
PIC24HJ32GP302/304,
PIC24HJ64GPX02/X04
and
PIC24HJ128GPX02/X04 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” (DS70247) of the “dsPIC33F/
PIC24H Family Reference Manual”,
which is available from the Microchip
website (www.microchip.com).
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.
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
