WebCPU: The CPU checks for pending interrupts at the beginning of an instruction. It answers the highest-priority interrupt, which has a higher priority than that given in the interrupt priority register. 2. Device: The device receives the acknowledgment and sends the CPU its interrupt vector. Webinstruction following an interrupt. The address of an ISR is defined in an interrupt vector. The MSP430 uses vectored interrupts where each ISR has its own vector stored in a vector table located at the end of program memory.
