Reserved
The value read from this bit is indeterminate. Do not set this bit.
ECOMn
Enable Comparator
Cleared to disable the comparator function.
Set to enable the comparator function.
CAPPn
Capture Positive
Cleared to disable positive edge capture.
Set to enable positive edge capture.
CAPNn
Capture Negative
Cleared to disable negative edge capture.
Set to enable negative edge capture.
MATn
Match
When MATn = 1, a match of the PCA counter with this Module's
compare/capture register causes the CCFn bit in CCON to be set, flagging an
interrupt.
TOGn
Toggle
When TOGn = 1, a match of the PCA counter with this Module's
compare/capture register causes theCEXn pin to toggle.
PWMn
Pulse Width Modulation Mode
Cleared to disable the CEXn pin to be used as a pulse width modulated output.
Set to enable the CEXn pin to be used as a pulse width modulated output.
CCF0
Enable CCF Interrupt
Cleared to disable compare/capture flag CCFn in the CCON register to generate
an interrupt.
Set to enable compare/capture flag CCFn in the CCON register to generate an
interrupt.
Reset Value = X000 0000b
