Abstract
A data transfer control device includes: an encoder circuit which performs encoding data and generation of a special code; a parallel/serial conversion circuit which converts parallel data from the encoder circuit to serial data; and a transmitter circuit which receives the serial data and transmits the special code and the data through the serial signal line. The transmitter circuit outputs an idle signal, logical level of which is continuously fixed at a first logical level in units of a given number of bits or more to the serial signal line as a signal indicating an idle state. The encoder circuit suspends operation after an indication that there is no transmission data by a transmission data valid/invalid signal from an upper layer circuit.
