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.
High-speed Output Mode
In this mode, the CEX output (on port 1) associated with the PCA module will toggle
each time a match occurs between the PCA counter and the module's capture registers.
To activate this mode the TOG, MAT, and ECOM bits in the module's CCAPMn SFR
must be set (see Figure 12).
A prior write must be done to CCAPnL and CCAPnH before writing the ECOMn bit.
