14.3 8-bit Compare Output (16-bit)
The MC80F0424/0432/0448 has a function of Timer Compare
Output. To pulse out, the timer match can goes to port pin(T0O,
PWM1O, T2O, PWM3O) as shown in Figure 14-4, Figure 14-5
and Figure 14-12. In this mode, the bit PWM1O and PWM3O of
PSR0 register should be set to “1”, and the bit PWM1E/PWM3E
of timer1/timer3 mode register (TM1/TM3) should be set to “0”.
These Compare output pins output the signal having a 50:50 duty
square wave, and output frequency is same as below equation.
