Abstract:
1. An interface circuit configured for communication of data in a bi-directional mode, comprising: a first bi-directional data terminal and a second bi-directional data terminal, the first and second data terminals each structured to be reversible and configurable during operation to send and receive data over time frames composed of intervals of time; and a control circuit coupled to the first and second data terminals to control the first and second data terminals during operation, such that, in a first mode of operation, the first data terminal is configured to send only and not to receive data and the second data terminal is configured to receive only and not to send data, while in a second mode of operation, the first data terminal is configured to receive only and not to send data, and the second data terminal is configured to send only and not to receive data, and in which the first and second data terminals are structured to switch from the first mode of operation to the second mode of operation or the reverse, from one time interval to another within the time frame.
