Pulse Width Modulator (PWM) Timing Parameters

Figure 67 depicts the timing of the PWM, and Table 71 lists the PWM timing characteristics.

The PWM can be programmed to select one of three clock signals as its source frequency. The selected

clock signal is passed through a prescaler before being input to the counter. The output is available at the

pulse width modulator output (PWMO) external pin.
