8-bit PWM (Pulse Width Modulation) Mode
This mode is valid only for timer 0 and timer 2. In this
mode, maximum two PWMs of 8-bit resolution
(PWM0 and PWM2) can be output.
PWM pulse is output to TO1 pin (also used as P55)
when using timer 0, and to TO3 pin (also used as P57)
when using timer 2.
Timer 1 and timer 3 can also be used as 8-bit timer.
As an example, the case of timer 0 will be explained
below. (Timer 2 also operates in the same way.)
Timer output is inverted when up-counter (UC0)
matches the set value of timer register TREG0 or when
2n - (n = 6, 7, or 8; specified by T01MOD
<PWM0,10>) counter overflow occurs. Up-counter
UC0 is cleared when 2n - 1 counter overflow occurs.
For example, when n = 6, 6-bit PWM will be output,
while when n = 7, 7-bit PWM will be output.
To use this PWM mode, the following conditions must
be satisfied.
(Set value of timer register) < (Set value of 2
overflow)
(Set value of timer register)
n
- 1 counter
