Timer0 as counter

WebThe 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. You can read or write values from/to this timer. Since it's an 8-bit timer, the TMR0 can count from 0 to 255 (2 8 = 256). Other microcontrollers have multiple timers with higher bit ...
