The interrupt service routine (ISR) is the software module that is executed when the hardware requests an interrupt. There may be one large ISR that handles all requests (polled interrupts), …

An interrupt in computer architecture is a signal that requests the processor to suspend its current execution and service the occurred interrupt. To service the interrupt the processor executes …

Interrupts pause the current program and transfer control to a specified user-written firmware routine called the Interrupt Service Routine (ISR). The ISR processes the interrupt event, then …

In soft real-time systems, the response to an event may be specified as a range of acceptable times. The interrupt routine can suspend the main loop and execute at any time.

Interrupt-service routine (ISR) or device driver function The system awakens and activates on an interrupt through a hardware or software signal. The system on port interrupt collects the coin …

If you want to set the mask bit of an interrupt, i.e., you enable a certain interrupt, then you must write a corresponding ISR (interrupt service routine). The table contains the address of the ISR …

In order to detect an interrupt overload such as a stuck key and preventing it from interfering with the system timeliness, the keyboard interrupt service routine is extended with a component...
