AHB Interrupt Controller

with No Comments

Overview

The PE-INT-AHB is a Programmable Interrupt Controller which adopts AMBA AHB bus. PE-INT-AHB supports two types of interrupt: Fast Interrupt Request and Normal Interrupt Request with vectored control. Specially, it can connect directly to CPU for handling interrupt faster and connect to the other to expand the number of interrupt sources.
