Input/output data port with a parallel and serial interface |
摘要 |
The present invention disclosed an input/output data port circuit which connects a parallel data bus with an input serial data bus and an output serial data bus. The input/output data port is selectively operable in either a linear mode or a buffered mode. The input/output port is comprised of an interface register that is connected to a parallel data bus, a serial input bus and a serial output bus; a temporary register that is serially connected to the interface register, an outbound register that is connected in parallel to the temporary register and serially connected to a serial bus; and an inbound register that is connected in parallel to the temporary register and serially connected to a serial, bus.
