Overview

The IPC-IntrCtrl-AHB is a programmable interrupt controller designed to interface to an AMBA AHB bus. The interrupt function is necessary for any embedded microprocessor based SOC that is running a Real Time Operating System (RTOS).
The IPC-IntrCtrl-AHB Interrupt Controller is fully scalable to support 1 to 32 interrupt sources and provides a programmable interrupt register which can be used to generate an interrupt under software control. The IPC-IntrCtrl-AHB Interrupt Controller provides separate enable set and enable clear mechanisms to prevent dangerous read-modify-write operations within the critical interrupt system. Active high and active low interrupt request outputs are available to facilitate cascading of multiple interrupt controllers in order to support more than 32 interrupt sources.

Features

Programmable Interrupt Controller

Scalable (from 1 to 32 interrupts)
