data register (PWMD). If the values in the PWMD register are not zero, an overflow of the 8bits of
counter causes the PWM output to toggle from Low level to High level. In this way, the reference value
written to the reference data register determines the module's base duty cycle.

The PWM output signal toggles to Low level whenever the 8bits of counter matches the reference
