WebDec 7, 2016 · ISR: Stands for "Interrupt Service Routine." An ISR (also called an interrupt handler) is a software process invoked by an interrupt request from a hardware device. It handles the request and sends it to the CPU , interrupting the active process . When the ISR is complete, the process is resumed. WebThe interrupt system priorities are determined by hardware. Furthermore, all interrupt handlers have priority over the operating system processes, since an interrupt will be automatically fielded unless the interrupts are masked. As a result, an RTOS must be carefully architected so that interrupts do not subvert the operating system’s scheduler.
