6.5.2. 16-bit Software Timer / Compare Mode
The PCA modules can be used as software timers by setting both the ECOM 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 (See Figure 10).
