WebThe ,, RST/NMI pin should never be held permanently 'low'. When a situation happens that activates the PUC, the consecutive reset of the bits in WDTCTL register forces the reset … Web7. The CPU has a Non-Maskable Interrupt (NMI) pin (or hardware equivalent) that is used to trigger an NMI. There is external circuitry (or hardware equivalent) to prevent NMIs from reaching the CPU. Since the 80286 the mechanism used was through IO ports associated with the CMOS/Realtime Clock (RTC) controller.

WebJan 16, 2024 · An NMI is reserved for well defined situations - either because they are dead end anyway (like a memory fault or a power outage) or because the system is defined to work that way. A general purpose computer will be of the first kind, while an embedded system might be of the later. Game consoles are as well embedded systems.

WebThe NMI is an edge-triggered input that requests an interrupt on the positive edge (0-to-1 transition). After a positive edge, the NMI pin must remain logic 1 until it is recognized by the microprocessor. The NMI input is often used for parity errors and other major system faults, such as power failure. Power failures are easily detected by ...
