Functions
void	icuInit (void)
	Initialize ICU unit and disable all interrupts.

	Disable a peripheral IRQ.

void	icuIrqSetup (u16 mask, int index)
	Route a peripheral IRQ to a CPU IRQ.

Detailed Description

ICU helpers.

The ICU helpers allow the developer to route peripheral interrupts (APBP, DMA, etc) to CPU interrupts 0 to 2.

Function Documentation

void icuIrqDisable ( u16 mask )

Disable a peripheral IRQ.

Parameters

mask	Interrupt mask. For example, ICU_IRQ_MASK_APBP.

Route a peripheral IRQ to a CPU IRQ.

The interrupt is setup as edge-triggered and normal polarity.

Parameters

mask	Interrupt mask. For example, ICU_IRQ_MASK_APBP.
index	CPU interrupt to be triggered for the specified mask (0 to 2).
