Hardware Interrupts
Hardware interrupt is caused by any peripheral device by sending a signal through a specified pin to the microprocessor. ... NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority. One more interrupt pin associated is INTA called interrupt acknowledge.
What is the use of intr pin?
INTR : Interrupt Request. This is triggered input. This is sampled during the last clock cycles of each instruction for determining the availability of the request. If any interrupt request is found pending, the processor enters the interrupt acknowledge cycle.
What is Inta in microprocessor?
Short for INTerrupt Acknowledge, INTA is a signal used to identify that a CPU has an interrupt made by the interrupt controller.
