Reserved
The value read from this bit is indeterminate. Do not set this bit.
Enable Comparator
Cleared to disable the comparator function.
Set to enable the comparator function.
Capture Positive
Cleared to disable positive edge capture.
Set to enable positive edge capture.
Capture Negative
Cleared to disable negative edge capture.
Set to enable negative edge capture.
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.
Toggle
When TOGn = 1, a match of the PCA counter with this Module's
compare/capture register causes theCEXn pin to toggle.
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.
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.
