To use one of the PCA modules in the capture mode
CCAPM bits CAPN and CAPP for that module must be set. The external CEX input for the
module (on port 1) is sampled for a transition. When a valid transition occurs the PCA
hardware loads the value of the PCA counter registers (CH and CL) into the module’s
capture registers (CCAPnL and CCAPnH).

Description
Reserved for future use. Should be set to ‘0’ by user programs.
Enable Comparator. ECOMn = 1 enables the comparator function.
Capture Positive, CAPPn = 1 enables positive edge capture.
Capture Negative, CAPNn = 1 enables 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. PWMn = 1 enables the CEXn pin to be
used as a pulse width modulated output.
Enable CCF Interrupt. Enables compare/capture flag CCFn in the
CCON register to generate an interrupt.
