Webb13 juli 2024 · A Non-Maskable Interrupt (NMI) is a hardware interrupt that cannot be ignored by the processor. These types of interrupts are usually reserved for very important tasks and to report hardware errors to the processor. Depending on the make and model of the system, you may be able to deliberately send an NMI to the CPUs. Webb14 nov. 2024 · An Interrupt Request is necessary for things like keyboard presses, mouse movements, printer actions, and more. When the request is made by a device to momentarily stop the processor, the computer is then able to give the device some time to run its own operation.

Practicle example: Imagine we received 10 bytes at 115200 bauds. Each byte at 115200 bauds takes about 10us on UART line, total 100us.

WebbIn edge-triggered mode, the interrupt is “noticed” only once, at step 1. Only when the interrupt line is cleared, and then reasserted, does the PIC consider another interrupt to have occurred. Neutrino allows ISR handlers to be stacked , meaning that multiple ISRs can be associated with one particular IRQ.
