Registers used in 8259
The 8259 is a programmable interrupt controller. It was designed to manage multiple interrupt requests from various peripheral devices in a computer system. 8259 is a programmable interrupt controller which has a unique style. Some certain interrupt conditions regulate the interrupt levels as well. These interrupt levels are also known as the edge-triggered interrupt where the masking process is related to the individual interrupt bits with 64 pins. In this article, we are going to discuss the Registers used in 8259 in detail.
