WebThe 8051 has two counters/timers which can be used either as timer to generate a time delay or as counter to count events happening outside the microcontroller. The 8051 has … WebIn 8051, the oscillator output is divided by 12 using a divide by 12 network and then fed to the Timer as the clock signal. That means for an 8051 running at 12MHz, the timer clock input will be 1MHz. That means the the timer advances once in every 1uS and the maximum time delay possible using a single 8051 timer is ( 2^16) x (1µS) = 65536µS.
WebFor details on how this works, you can look at Atmel's Hardware Guide for the 8051. While it's specific to their implementation, most implementations are pretty close (they all try to keep the original semantics of the original 8051 micro). On page 2-112 they talk about interrupts are handled. Section 2.16.1 says: WebThe programming of 8051 Timers can be done by using either polling method or by using interrupt. In polling, the microcontroller keeps monitoring the status of Timer flag. While …

WebThe 8051 has two timers, Timer 0 and Timer 1. They can be used as timers or as event counters. Both Timer 0 and Timer 1 are 16-bit wide. Since the 8051 follows an 8-bit architecture, each 16 bit is accessed as two separate registers of low-byte and high-byte. Timer 0 Register The 16-bit register of Timer 0 is accessed as low- and high-byte.
