Table 52 shows the CCAPMn settings for the various PCA functions.
Table 51. CCAPMn Registers (n = 0-4)
CCAPM0 - PCA Module 0 Compare/Capture Control Register (0DAh)
CCAPM1 - PCA Module 1 Compare/Capture Control Register (0DBh)
CCAPM2 - PCA Module 2 Compare/Capture Control Register (0DCh)
CCAPM3 - PCA Module 3 Compare/Capture Control Register (0DDh)
CCAPM4 - PCA Module 4 Compare/Capture Control Register (0DEh)

the CAPP bit enables the positive edge. If both bits are set both edges will be
enabled and a capture will occur for either transition.
The last bit in the register ECOM (CCAPMn.6) when set enables the comparator
function.

Description
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 the CEXn 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.
