Timer 1 can also be used as an 8-bit timer. When using timer 2, the PWM pulse is
output to the TO3 pin (also used as P83). The operation of timer 2 will be explained
below. Timer 3 can also be used as an 8-bit timer.

This mode is valid only for timer 0 and timer 2. In this mode, the maximum 8-bit
When using timer 0, the PWM pulse is output to the TO1 pin (also used as P67).
Timer output is inverted when the up counter (UC2) matches the set value of timer
To use this PWM mode, the following conditions must be satisfied.
Figure 3.7.17 shows the block diagram of operations in this mode.
