8051 microcontroller interrupt system structure and interrupt control principle
When several interrupt sources request interrupts from the CPU at the same time, they are queued according to the priority of the real-time events that occur, and the interrupt requests for the most urgent events are processed first, so the microcontroller specifies the priority level of each interrupt source. When
