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.
The PCA modules can be used as software timers
and MAT bits in the modules CCAPMn register. The PCA timer will be compared to the
module’s capture registers and when a match occurs an interrupt will occur if the CCFn
(CCON SFR) and the ECCFn (CCAPMn SFR) bits for the module are both set.
