Detailed explanation-1: -The PIC16F877A basically has three timer modules. These timer module terminals are also multiplexed with other functions for handling alternate functions. These three-timer modules as named as TIMER 0, TIMER 1 and TIMER 2.
Detailed explanation-2: -The PIC16F877A PIC MCU has three Timer Modules. They are names as Timer0, Timer1 and Timer2. The Timer 0 and Timer 2 are 8-bit Timers and Timer 1 is a 16-bit Timer.
Detailed explanation-3: -The PIC16F84A has one 8-bit free-running timer named TMR0. The term “free-running” means it continually runs on the background and has no start or stop control.
Detailed explanation-4: -Calculate the Timer Count for the required delay. Set the Presaclar bits in OPTION REG as per the delay calculations. Clear the PSAbit for using the prescalar. Select the Clock Source Internal/External using TOCS bit. Load the timer value into TMRO register. Enable the Timer0 Interrupt by setting TMR0IE bit. More items
