counter overflow.
This mode, only available for TMRA0, can output PWM pulses with up to 8-bit resolution. PWM
In this mode TMRA1 can be used as an 8-bit timer.
Timer output is inverted when the up-counter UC0 and the value set in the timer register TA0REG
Before PWM mode can be used, the following conditions must be satisfied:
(TA0REG set value) < (2
(TA0REG set value) ≠ 0
