[PWM] Normal Done State

In this state, the PWM function ramps down to zero.

On any transition into the Normal Done state, the PWM function starts ramping down. If frequency ramping is selected (PP=1), the lowest frequency generated is the mean frequency of the last pulse output before reaching zero.

When the PWM is executed in the Normal Done state the following occurs:

• If duty cycle ramping is selected (PP=0), the output duty cycle is monitored. When it reaches zero, the PWM function transitions to the Idle state.
• If frequency ramping is selected (PP=1), the output frequency is monitored. When it reaches zero, the PWM function transitions to the Idle state.
• The PWM output duty cycle or frequency is updated using the time since the start of the Done phase and Accel/Decel.
