11.5.3 8-Bit PWM Mode
The 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 P5FSR[4:3] bits. In the 8-bit timer/counter mode, a match signal is generated when the
counter value is identical to the value of T0DR. When the value of T0CNT and T0DR is identical 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”, and then continues incrementing from “00H”. The
timer 0 overflow interrupt is generated whenever a counter overflow occurs. T0CNT value is cleared by software
(T0CC) bit .
