<Notes>
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:

When the contents of the PWM register or PWM prescaler have changed,
the PWM output will change from the next period after the change.
(Count source selection bit = 0, where n is the value set in the prescaler)
(Count source selection bit = 1, where n is the value set in the prescaler)
