a8259 可编程中断控制 altera提供

The a8259 is designed to simplify the implementation of the interrupt interface  in 8088 and 8086  based microcomputer systems. The device is known as a programmable interrupt controller.  The a8259 receives and prioritizes up to 8 interrupts,  and in the cascade mode, this can be expanded up to  64 interrupts. An asynchronous reset and a clock input have been added to improve operation and reliability.
