WebFeb 14, 2024 · A non-maskable interrupt is a hardware interrupt that cannot be disabled or ignored by the instructions of CPU. 2: When maskable interrupt occur, it can be handled after executing the current instruction. When non-maskable interrupts occur, the current instructions and status are stored in stack for the CPU to handle the interrupt. 3 Web8085 supports multilevel interrupts. So, the interrupts are classified as: Hardware Interrupt: These interrupts are basically associated with peripheral devices generated at the time of …
WebFig 1: Pin diagram of 8085. The 6,7,8,9 and 10th pin, in Fig 1, are the hardware interrupt pins. That means you can connect your I/O devices to these pins, and write an ISR in their vectored ...
