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).
Figure 10. PCA Compare Mode and PCA Watchdog Timer
Before enabling ECOM bit, CCAPnL and CCAPnH should be set with a non zero value, otherwise an unwanted
match could happen. Writing to CCAPnH will set the ECOM bit.
Once ECOM set, writing CCAPnL will clear ECOM so that an unwanted match doesn’t occur while modifying
the compare value. Writing to CCAPnH will set ECOM. For this reason, user software should write CCAPnL first,
and then CCAPnH. Of course, the ECOM bit can still be controlled by accessing to CCAPMn register.
