uint32_t MXC_NVIC_GetVector

(

IRQn_Type

IRQn

)

Get Interrupt Vector.

Reads an interrupt vector from interrupt vector table. The interrupt number can be positive to specify a device specific interrupt, or negative to specify a processor exception.

Parameters

[in]

IRQn

Interrupt number.

Returns

Address of interrupt handler function

MXC_NVIC_SetVector()

void MXC_NVIC_SetVector	(	IRQn_Type	irqn,
		void(*)(void)	irq_callback
	)

Set an IRQ hander callback function. If the IRQ table is in flash, this will copy it to RAM and set NVIC to RAM based table.

Parameters

irqn	ARM external IRQ number
irq_callback	Function to be called at IRQ context
