dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
15.0 OUTPUT COMPARE
Note 1: This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 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” (DS70358) of the “dsPIC33E/
PIC24E Family Reference Manual”,
which is available from 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 one of eight
available clock sources 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.
Note 1: Only OC1, OC2, OC3 and OC4 can trigger
a DMA data transfer.
2: See Section 13. “Output Compare”
(DS70358) in the “dsPIC33E/PIC24E
Family Reference Manual” for OCxR and
OCxRS register restrictions.

Note 1: The Trigger/Sync source is enabled by default and is set to Timer2 as a source. This timer must be enabled for
proper OCx module operation or the Trigger/Sync source must be changed to another source option.
