6.10.4 Pulse width modulator mode

All of the PCA modules can be used as PWM outputs (Figure 31). Output frequency

depends on the source for the PCA timer.

All of the modules will have the same frequency of output because they all share one and

only 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
