I
Note
The PWM starts after the PWM function enable bit is set to enable and
L
level is output from the PWM pin.
The length of this
L
level output is as follows:
sec
(Count source selection bit = 0, where n is the value set in the prescaler)
sec
(Count source selection bit = 1, where n is the value set in the prescaler)
