MICROPROCESSOR AND MICROCONTROLLER

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: -The MAXQ family of microcontrollers has three types of timers: Timer 0, Timer 1, and Timer 2. The MAXQ Timer 0 type is modeled after the Timer 0 type common on many 8051 microcontollers.

Detailed explanation-5: -Timer2 is an 8-bit timer with a prescaler, a postscaler, and a period register. Using the prescaler and postscaler at their maximum settings, the overflow time is the same as a 16-bit timer. Timer2 is the PWM time-base when the CCP module(s) is used in the PWM mode.
