****************************************************************************

#define	STOP_LEVEL	7
#define	VECT_STOP	$47	; ABORT interrupt

;**************************************************

;If your board hardware requires you to clear the

;"read" interrupt, then you must include the necessary

;code inside the INT_RCLEAR macro below.

;**************************************************

INT_RCLEAR: macro endm

;**************************************************

;"stop" interrupt

;We will only stop the target if the ABORT switch is pressed. We

;will not stop for HOST_NMI or EXT_NMI interrupts.

;The Non-Maskable Interrupt status is in the NMI_STATUS register

;which is in even-byte locations at NMI_STATUS. Bit #0 of the

;first byte at NMI_STATUS indicates that the ABORT switch was pressed.
