timer0 question
PostPosted: Fri Jan 09, 2004 7:27 pm     Reply with quote
Hi all
Is there a way to make timer0 faster than the clock? I mean, is there a way to multipy the frequency by 2, or 4? I have a 4 MHz xtal and I want to get timer0 at 2 or 1 MHz.
Thanks

Hello

From the datsheet (PIC16F84A):
In Timer mode, the Timer0 module will increment every instruction cycle (without prescaler).

So at 4MHz xtal, the maximum incrementing frequency would be 1MHz. If you want it faster, use a faster crystal.
