Pulse Width Modulators (PWMs)
11.5 PWMs during Wait Mode
11.6 PWMs during Stop Mode
11.7 PWMs during Reset
Advance Information
The PWM continues normal operation during wait mode. To decrease
power consumption during wait mode, it is recommended that the rate
select bits in the PWM control registers be cleared if the PWM is not
being used.
In stop mode, the oscillator is stopped causing the PWM to cease
functioning. Any signal in process is aborted in whatever phase the
signal happens to be in.
Upon reset the PSA0X and PSA1X bits in PWMX control registers are
cleared. This disables the PWM system and sets the PWM outputs low.
The user should write to the data registers prior to enabling the PWM
system (for example, prior to setting PSA1X or PSA0X). This will avoid
an erroneous duty cycle from being driven.
