Abstract:
1. A data transfer method comprising: multiplexing a data character having a bit width M and a control character having a bit width N, and adding a control character valid signal indicating whether the control character is valid, in order to generate a symbol code having a bit width M+1 or N+3, whichever is greater, where M is a natural number greater than or equal to 3, and N is a natural number greater than or equal to 1; and making a data transfer by converting the symbol code from parallel data into serial data, and outputting the serial data to a transmission line, wherein an inverted value of a predetermined bit of the data character is used as a value of the control character valid signal when transferring the data character, a value of the predetermined bit of the data character is used as the value of the control character when transferring the control character, and the control character is represented by bits other than the predetermined bit.
