Functional Description

6.8.5.1 PWM Prescaler
PWM prescaler is used to divide clock source, prescaler counting CLKPSC +1 times, PWM counter
only count once. The pre-scale double buffer is setting by CLKPSC (PWM_CLKPSCn[11:0], n = 0,
2, 4) bits. Figure 6.8-6 is an example of PWM channel 0 prescale waveform. The prescale counter
will reload CLKPSC at the begin of the next prescale counter down-count.
