Introduction to Programmable Interrupt Controller

A Programmable Interrupt Controller (PIC) has been designed and can be used to handle many interrupts at a time. This controller handles all simultaneous interrupt requests along with their priorities and the microprocessor will be relieved from this task. The Programmable Interrupt Controller (PIC) functions as an overall manager in an interrupt-driven system environment.
