"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.
