; **************************************************
; If your board hardware requires you to clear the
; "read" interrupt, then you must include the necessary
; code inside the INT_RCLEAR macro below.

; **************************************************
; "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.
