ABSTRACT:
A bi-directional serial interface for serial communication having a control line to facilitate the transmission of data to and from a microcontroller and a serial interface module. The control line can be used by both the microcontroller and the serial interface module to send controlling signals such as start signals, receipt acknowledge signals, error signals, and stop signals. By having a dedicated control line that can be used by both the sending device and the receiving device, the present invention allows the initiation of a communication session by either the microcontroller or the serial interface.
