In this section we use interrupts to program the 8051 timers. Notice the following points about the program in Example 11-2. 1. This example program shows how to configure timer/counter 0 as a 16-bit timer. An interrupt service routine (ISR) is invoked each time the timer overflows (goesExample 1: Timer Interrupts To demonstrate use of timer interrupts, we will blink a LED1 connected to P0.0 at 50ms(using timer zero) and in the mean time we PROGRAMMING 8051 TIMERS. • Basic registers of the timer. – Timer 0 and Timer 1 are 16 bits wide. – each 16-bit timer is accessed as. The timer interrupt is an 8051 hardware feature where the CPU will execute special code, called an interrupt service routine, when the overflow flag bit is set
