Detailed Description

Programmable Interrupt Controller (PIC) definitions for the BEEP-8 system.

This file contains the definitions for the Programmable Interrupt Controller (PIC) in the BEEP-8 system. It provides macros for accessing PIC registers, which are used to control and handle hardware interrupts.

The PIC is located at a specific memory address and includes registers for device control (DCR), interrupt acknowledge (IAR), and end of interrupt (EOIR).

For more detailed information, please refer to the BEEP-8 data sheet.
