WebCPU is a busy taskmaster. Any subsystem requiring the attention of the CPU generates Interrupt. INTERRUPT (INT) is both a control and status signal to the CPU. Generally, the memory subsystem does not generate Interrupt. The Interruption alters the CPU execution flow. Recognising and servicing Interrupts is fundamental to any processor design. WebA hardware interrupt is a signal that stops the current program forcing it to execute another program immediately. The interrupt does this without waiting for the current program to finish. It is unconditional and immediate which is why it is called an interrupt - it interrupts the current action of the processor. kymco user manual https://jd-equipment.com
