Abort Push Button (SW2)
When the Abort button (SW2) on the faceplate is pressed, it enables an NMI interrupt to the host
CPU controller.
The Watchdog Timer (Port 79h)
The watchdog timer can be programmed through the Watchdog Register (Port 79h, bit 4) to
generate a non-maskable interrupt if it is not strobed within a given time-out period. The Watchdog
