11.2 16-bit Software Timer Comparator Mode
The PCA modules can be used as software timers by setting both the ECOM and MAT bits in the
CCAPMn register.

Figure 11-3 PCA 16-bit Timer Comparator Mode
In this mode, the PCA timer is compared to the module’s capture registers. When a match occurs, an
interrupt is generated if the CCFn (CCON) and ECCFn (CCAPMn) bits are set.
11.3 High Speed Output Mode
To activate this mode, the TOG, MAT, and ECOM (CCAPMn) bits must be set.
