11.1.2 8-bit PWM mode
Timer 0 has a high speed PWM (Pulse Width Modulation) function. In PWM mode, T0O/PWM0O pin
outputs up to 8-bit resolution PWM output. This pin should be configured as a PWM output by setting
the T0O/PWM0O function by P3FSRH[0] or P3FSRL[4] bits.
In 8-bit timer/counter mode, a match signal is generated when the counter value is identical to the
value of T0DR. When values of T0CNT and T0DR are identical to each other in timer 0, a match
signal is generated and the interrupt of timer 0 occurs.
In PWM mode, the match signal does not clear the counter. Instead, it runs continuously, overflowing
at “FFH”. Then the counter continues incrementing from “00H”. The timer 0 overflow interrupt is
generated whenever a counter overflow occurs. T0CNT value is cleared by software (T0CC) bit.
