Function Documentation

int isrDisp_init

(

isrDisp_t *

pThis

)

Initialize isr dispatcher Parameters:.

Parameters:

pThis

pointer to own object

Returns:

Zero on success. Negative value on failure.

int isrDisp_printIrqFreq

(

isrDisp_t *

pThis

)

isrDisp_printIrqFreq prints number of occured interrupts for each registered IRQ

Parameters:

Returns:

None

int isrDisp_registerCallback	(	isrDisp_t *	pThis,
		e_isr_t	id,
		tFuncPtr	pFunc,
		void *	pArg
	)

Register interrupt handler for ISR for DMA 3 Parameters:.

Parameters:

	pThis	pointer to own object
	pFunc	pointer to function to call
	pArg	pointer to argument passed on call

Returns:

Zero on success. Negative value on failure.

Parameter Check

Parameter Check

Assign the new function pointer to the ISR Dispatcher

find out which isr mask has to be set to enable the interrupt

int isrDisp_unregisterCallback	(	isrDisp_t *	pThis,
		e_isr_t	id
	)

isrDisp_unregisterCallback The function does parameter check and then unregisters the function.

We ISR wont be able to interrupt the function again Parameters:

Returns:

None

Parameter Check

Find out whcih register has to be used to disable the interrupt

Unregister the function from the table
