6.5.1. PCA Capture Mode
To use one of the PCA modules in the capture mode either one or both of the 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). If the CCFn bit for the module in the CCON
SFR and the ECCFn bit in the CCAPMn SFR are set then an interrupt will be generated (Refer to Figure 9).
