sdl_interrupt_priv.h File Reference

Introduction

This file contains the internal defines for configuring interrupt support for the ARM Cortex-R5 and VIM.

The following is the recommended calling sequence for this API:

1. Call Intc_Init() to initialize the interrupt support
2. For each interrupt you wish to enable... a. Call Intc_IntSetSrcType() to set interrupt type (level or pulse) b. Call Intc_IntPrioritySet() to set the interrupt priority (0-15) and mapping (IRQ or FIQ) c. Call Intc_IntRegister() to register the interrupt d. Call Intc_IntEnable() to enable the interrupt
3. Call Intc_SystemEnable() to enable the R5 IRQ and FIQ interrupts

When an interrupt occurs, control goes to the ISR given as a parameter in the Intc_IntRegister() call for that specific interrupt. The pending interrupt is automatically cleared and acknowledged in the VIM.

Other calls available: o Call Intc_IntUnregister() to unregister a previously registered interrupt o Call Intc_IntDisable() to disable a previously enabled interrupt o Call Intc_SystemDisable() to disable the R5 IRQ and FIQ interrupts
