Notes on Use

When using the timer output as variable duty-cycle pulse (PWM) output, note the following point. From

the update of the timer write register until the occurrence of the overflow interrupt, the PWM output differs

from the period and duty settings, as shown in table 24. The PWM output should therefore not be used until

after the overflow interrupt following the update of the timer write register. After the overflow, the PWM

output will have the set period and duty cycle.
