The assembly language is a low-level programming language used to write program code in terms of mnemonics. Even though there are many high-levellanguages that are currently in demand, assembly programming language is popularly used in many applications. It can be used for direct hardware manipulations. It is also used to write the programming code efficiently with less number of clock cycles by consuming less memory compared to the other high-level languages. The assembly language is a fully hardware related programming language.

Timers in 8051 ppt to pdf

In some cases a timer is needed to measure elapsed time; in others we want to count or time some external events. Here's a primer on the hardware. In some cases, a timer measures elapsed time counting processor clock ticks. In others, we want to count or time external events. The names counter and timer can be used interchangeably when talking about the hardware. The difference in terminology has more to do with how the hardware is used in a given application.

8051 Timers and Counters

The has two timers: timer0 and timer1. They can be used either as timers or as counters. Both timers are 16 bits wide. Since the has an 8-bit architecture, each bit is accessed as two separate registers of low byte and high byte. First we shall discuss about Timer0 registers.

They can be used as 1. The timer is used as a time delay generator. External input from input pin to count the number of events on registers. These clock pulses cold represent the number of people passing through an entrance, or the number of wheel rotations, or any other event that can be converted to pulses. Because the input of timer is a regular, fixedperiodic square wave, we can count the number of pulses and calculate the time delay.

A timer is a specialized type of clock used for measuring specific time intervals. Timers can be categorized into two main types. A timer which counts upwards from zero for measuring elapsed time is often called a stopwatch , while a device which counts down from a specified time interval is more usually called a timer. A simple example of this type is an hourglass. Working method timers have two main groups: Hardware and Software timers.
