(Changes “H” term from “A” to “B”.)
(Changes PWM period from “T” to “T2”.)
When the contents of the PWM register or PWM prescaler have changed, the PWM
output will change from the next period after the change.

Note
The PWM starts after the PWM 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)
