Table 41.
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
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.
