PIC24FJ16MC101/102 AND PIC24FJ32MC101/102/104
14.0 OUTPUT COMPARE
Note 1: This data sheet summarizes the features
of the PIC24FJ16MC101/102 and
PIC24FJ32MC101/102/104 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” (DS39706) of the “PIC24F
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com).
2: It is important to note that the
specifications in Section 26.0 “Electri-
cal Characteristics” of this data sheet,
supercede any specifications that may be
provided in PIC24F Family Reference
Manual sections.
3: 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
