Clocking timer 2 or 3 from timer 0
PostPosted: Fri Dec 28, 2007 12:47 pm     Reply with quote

Is it possible to clock hardware timers 2 & 3 at the relatively infrequent rate "timer0 on an 18F2520? In other words, "increment timer 2 at the same instant as timer0".

I will elaborate if necessary.

yes i agree. the difficulty is timer 2 has a maximum prescale of 16. i need to set timer 2 to a prescaler value of 32. hence why i need to clock from another source. I don't think its possible in strainght hardware, but i'm looking into 'exernal clocking'.
