14.3 8-bit Compare Output (16-bit)
The MC80F0208/16/24 has a function of Timer Compare Output.
To pulse out, the timer match can goes to port pin( T3O) as shown
in Figure 14-5 . Thus, pulse out is generated by the timer match.
These operation is implemented to pin, PWM3O/T3O.
In this mode, the bit PWM3O/T3O of R5 Port Selection register0
(PSR0.7) should be set to "1", and the bit PWM3E of timer3
mode register (TM3) should be set to "0". This pin output the sig-
nal having a 50 : 50 duty square wave, and output frequency is
same as below equation.
