Function Documentation

STATUS isrIntConnect	(	isrRoutingInfo_t *	pRoutingInfo,
		ULONG	intLvl,
		VOIDFUNCPTR	isr,
		int	parm
	)

Connect ISR to interrupt level.

----------------------------------------------------------------------------

This routine connects an interrupt service routine (ISR) to the specified interrupt level. Interrupt levelss are enabled separate from this routine. The interrupt level being connected should not be enabled when this routine is called. The specified ISR will get control with interrupts disabled.

Parameters:

	pRoutingInfo	- Pointer to the interrupt routing infomation..
	intLvl	- The interrupt level (0-31, 0=LSB).
	isr	- Pointer to the ISR.
	parm	- A user-defined parameter to pass to the ISR when the interrupt occurs.

----------------------------------------------------------------------------

void isrRouteInterrupt	(	isrRoutingInfo_t *	pRoutingInfo,
		TRC_cb_Exception *	rtn,
		unsigned long long	tim,
		unsigned int	fui
	)

Route an interrupt via a jump table.

Parameters:

	pRoutingInfo	(in) Routing jump table
	rtn	(in) Trace recording callback
	tim	(in) Timestamp to record in trace
	fui	(in) Format of trace record (as unsigned int)

This routine uses a jump table to route a set of aggregated interrupts. See isrRouter.h for underlying assumptions.
