Chapter 19 Pulse-Width Modulator (S12PWM8B8CV1)
1. Intended for factory test purposes only.
19.3.2.1
Each PWM channel has an enable bit (PWMEx) to start its waveform output. When any of the PWMEx
bits are set (PWMEx = 1), the associated PWM output is enabled immediately. However, the actual PWM
waveform is not available on the associated PWM output until its clock source begins its next cycle due to
the synchronization of PWMEx and the clock source.
