Communication system with automatic restoring function against faulty operation and restoring method thereof

A communication system, comprising:

• a master device for transmitting a reference clock through a clock line, transmitting and receiving data through a data line, and receiving input data through the data line;
• and
• a slave device for detecting human input data, transmitting and receiving the data in synchronization with the reference clock, and generating and transmitting the input data and a detection signal for reporting an operating state error, the slave device having set error verification data,
• wherein when the slave device detects an error using the error verification data, the slave device generates and transmits the detection signal to the master device, and the master device initializes the slave device in response to the detection signal.

A method of restoring a communication system including a master device for transmitting a reference clock and data and requesting and receiving input data and error detection data, and a slave device for detecting human input data, receiving the data in synchronization with the reference clock and generating and transmitting the input data, the method comprising:

• a data setting step of initializing the master device and the slave device, and storing, at the slave device, the error detection data for detecting a malfunction;
• an error detection step of requesting and receiving, at the master device, the error detection data and determining whether or not the error detection data is changed;
• and
• an initialization step of initializing, at the master device, the slave device according to whether or not the error detection data is changed.

A method of restoring a communication system including a master device for transmitting a reference clock and data and requesting and receiving input data, and a slave device for detecting human input data, receiving the data in synchronization with the reference clock, generating and transmitting the input data, and having set error verification data, the method comprising:

• a data setting step of initializing the master device and the slave device and storing error detection data for detecting a malfunction of the slave device;
• an error detection step of comparing, at the slave device, the error verification data with the stored error detection data and outputting a detection signal according to whether or not the error verification data is the same as the error detection data;
• and
• an initialization step of initializing, at the master device, the slave device in response to the detection signal.
