What is the interrupt priority?

Collection Like

Interrupt priority refers to the order in which interrupt requests should be processed when multiple interrupt requests occur at the same time. When multiple interrupt requests arrive at the same time, the system needs to determine which interrupt to process first based on the interrupt priority. Interrupt priority is usually set by hardware or software. In hardware priority, each interrupt signal line has a corresponding hardware interrupt priority, and interrupt requests with high priority will be responded to first. In software prioritization, the operating system or program sets the priority of interrupts programmatically.
