ABSTRACT:
An electronic device of detecting contention of a bidirectional bus for avoiding failing to drive a bidirectional bus due to bus contention includes: an output terminal, an input terminal and a data output unit, a timing comparing controller and a comparing unit. The output terminal is coupled to the bidirectional bus and used for outputting a data output signal to the bidirectional bus. The input terminal is coupled to the output terminal and the bidirectional bus and used for receiving a data reception signal from the bidirectional bus. The data output unit is used for providing the data output signal. The timing comparing controller is used for generating a timing comparison signal according to the data output signal. The comparing unit is used for comparing the data reception signal with the data output signal according to the timing comparison signal to determine a contention state of the bidirectional bus.
