INT 02 C - external hardware - NON-MASKABLE INTERRUPT Desc: generated by the CPU when the input to the NMI pin is asserted Notes: return address points to start of interrupted instruction on 80286+ on the 80286+, further NMIs are disabled until the next IRET instruction, but one additional NMI is remembered by the hardware and will be serviced after the IRET instruction reenables NMIs maskable interrupts may interrupt the NMI handler if interrupts are enabled although the Intel documentation states that this interrupt is typically used for power-failure procedures, it has many other uses on IBM-compatible machines: Memory parity error: all except Jr, CONV, and some machines without memory parity Breakout switch on hardware debuggers Coprocessor interrupt: all except Jr and CONV Keyboard interrupt: Jr, CONV I/O channel check: CONV, PS50+ Disk-controller power-on request: CONV System suspend: CONV Real-time clock: CONV System watch-dog timer, time-out interrupt: PS50+ DMA timer time-out interrupt: PS50+ Low battery: HP 95LX Module pulled: HP 95LXTop
