If the PWMREG value is changed during PWM output, the PWMREG value is loaded into
REGLAT when the duty counter overflows (at the beginning of the next PWM cycle). The
following shows the PWMU output waveform when the PWMREG value is changed.
When the PWMPRE value is changed during PWM output, the PWM cycle changes from the next
cycle. When the clock generator counter underflows, the PWMPRE value is loaded into PRELAT.
The following shows the PRELAT update timing when the PWMPRE value is changed.
