These communication links are used to resolve the differences … WebA very simple, elegant, and fast way of servicing interrupts from the thread level is to have a thread dedicated to interrupt processing. The thread attaches the interrupt (via InterruptAttach()) and then the thread blocks, waiting for the ISR to tell it to do something.

WebAug 20, 2015 · Interrupts can occur at any time they are asynchronous. ISR’s can call for asynchronous interrupts. Interrupt service mechanism can call the ISR’s from multiple sources. ISR’s can handle both maskable and non maskable interrupts. An instruction in a program can disable or enable an interrupt handler call. WebThe amount of work performed in the interrupt handler should be kept to a minimum; specifically, only perform the time-critical aspect of servicing the device. At a minimum, the interrupt handler runs with the current interrupt level disabled, so running too much code may affect the performance of other critical interrupt handling, specifically it can add to …
