Detailní popis

Purpose

Methods and definitions for configuring interrupts using the Advanced Interrupt Controller (AIC).

Usage

1. Configure an interrupt source using AIC_ConfigureIT
2. Enable or disable interrupt generation of a particular source with AIC_EnableIT and AIC_DisableIT.

Poznámka:

Most of the time, peripheral interrupts must be also configured inside the peripheral itself.

Dokumentace funkcí

void AIC_ConfigureIT	(	unsigned int	source,
		unsigned int	mode,
		void(*)(void)	handler
	)

Configures an interrupt in the AIC. The interrupt is identified by its source (AT91C_ID_xxx) and is configured to use the specified mode and interrupt handler function. Mode is the value that will be put in AIC_SMRx and the function address will be set in AIC_SVRx. The interrupt is disabled before configuration, so it is useless to do it before calling this function. When AIC_ConfigureIT returns, the interrupt will always be disabled and cleared; it must be enabled by a call to AIC_EnableIT().

Parametry:

source	Interrupt source to configure.
mode	Triggering mode and priority of the interrupt.
handler	Interrupt handler function.
