ABSTRACT:
A serial bus Input/Output (I/O) system has multiple I/O devices which are all connected in daisy-chain fashion on a serial bus. These I/O devices service peripherals that may generate different interrupt requests or DMA requests to the system controller. These requests are encoded, serialized and transmitted to the system controller on the serial bus, allowing the system controller to service a large number of interrupt requests and DMA requests via the serial bus with a very small number of external pins.
