Abstract
A signal transferring circuit for transferring data from a central system to electronic units coupled in series is disclosed. The signal transferring circuit comprises a first terminal for receiving a data signal and a second terminal for transmitting the data signal. It further comprises a first buffer having an input terminal and an output terminal. The input terminal is coupled to the first terminal, and the first buffer is enabled to transfer the data signal from the first terminal to a predetermined destination under a first condition. The signal transferring circuit also comprises a second buffer having an input terminal that is coupled to the predetermined destination and an output terminal that is coupled to the second terminal. The second buffer is enabled for transferring the data signal from the predetermined destination to the second terminal under the first condition. The signal transferring circuit further comprises a third buffer having an input terminal coupled to the first terminal and an output terminal coupled to the second terminal. The third buffer is enabled under a second condition to transfer the data signal from the first terminal to the second terminal.
