If you understand my question and if you know the answer, please tell me!
I wanna know what is the clock input of the timers below. Is it the primary clock(div by 4, of course) or the internal clobk(also div by 4)?
timer0
timer1
timer2
timer3
thanks |

You have to look at the diagrams in the PIC datasheet for part you're using. In looking at 1 that I use, 18F4520, it shows that all peripherals, which would include the timers, are driven from the same clock as CPU. That can be from all the usual oscillator and PLL modes.
But also, looking at block diagram of each timer module, they can accept 'Fosc/4' CPU clock or various other clocking options. |
