Timer 0 Querry
Posted: 17 Oct 2010 04:16
Dear readers
I have a small doubt with timer..
The timer0 of a P16F877a is configured with internal clock source and a Prescaler 1:2 with a Fosc = 1 Mhz.
The datasheet specifies that the Timer0 register reads from 255 - 0 and then rolls over.
when a Value is being entered in the timer0 register.. for example 200 ..
A)does the timer read from 255 to 200 and then rolls over.? setting up the INT flag ..
B)When the timer0 Register is observed on a LCD .. the value goes even below 200 ? How ?
Ur gudiance will be most welcome.
