WebOnce the interrupt has been serviced, the CPU restores the saved program state and resumes normal program execution. 2. When a system receives multiple interrupts, the CPU follows a predetermined priority scheme to determine which interrupt to service first. Interrupts with higher priority are serviced before interrupts with lower priority. WebSep 27, 2024 · 01. ISR had the capability of disabling the other devices’ interrupts while enabling the present device interrupts and it can re-enable the other device interrupts after completion of execution. 02. Interrupt_Service Routines are always ready to act because the maximum number of interrupts is of asynchronous type. 03.
