14.4.3. High Speed Output Mode
In this mode the CEX output 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 register must be set.

14.4.4. PWM Mode
All of the PCA modules can be used as PWM outputs. The frequency of the output depends on the clock source
for the PCA timer. All of the modules will have the same frequency of output because they all share the PCA
timer.
The duty cycle of each module is determined by the module‘s capture register CCAPnL and the extended 9^th bit,
ECAPnL. When the 9-bit value of { 0, [CL] } is less than the 9-bit value of { ECAPnL, [CCAPnL] } the output will
be low, and if equal to or greater than the output will be high.
