All of the PCA modules can be used as PWM outputs
depends on the source for the PCA timer.
All of the modules will have the same frequency of output because they all share only one
PCA timer. The duty cycle of each module is independently variable using the module’s
capture register CCAPnL. When the value of the PCA CL SFR is less than the value in the
