The 8051 Microcontroller And Embedded Systems Interrupts Programming The document discusses the concept of interrupts in the 8051 microcontroller, detailing various sources of interrupts and the differences between interrupt handling and polling methods.

An Introduction To Interrupt Programming On The 8051 Microcontroller Interrupts programming • an interrupt is an external or internal event that interrupts the microcontroller to inform it that a device needs its service. interrupts vs. polling • a single microcontroller can serve several devices. Write a program in which the 8051 reads data from p1 and writes it to p2 continuously while giving a copy of it to the serial com port to be transferred serially. Interrupt priorities what if two interrupt sources interrupt at the same time? the interrupt with the highest priority gets serviced first. all interrupts have a default priority order. priority can also be set to high or low. 126 interrupt sfrs interrupt enables for the 5 original 8051 interrupts timer 2 serial (uart0) timer 1 external 1 timer. • an interrupt is an external or internal event that interrupts the microcontroller to inform it that a device needs its service. • a set of program instructions written to service an interrupt is called the interrupt service routine.

It outlines various types of interrupts including vectored, non vectored, maskable, and non maskable, as well as the steps for executing an interrupt and handling external hardware interrupts.
