Table 41.
To use one of the PCA modules in the capture mode
CCAPM bits CAPNn and CAPPn 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
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.
