All of the PWMs feature push-pull. Outputs from all PWMs are staged by one PVCO
clock. The repetition frequency of the PWM output signals can be calculated from the
following equation:
When reset, PWM_data registers are not initialized; however, PWM output is set to 0.
Because the PWM is clocked with PVCO, it is better to initialize the PWM_data before
enabling PVCO.
Table 36 lists the bits for the shadow control register.
Table 37 lists the bits for the CGROM offset register.
