Abstract:
The invention has been made to solve a problem that as the cycle of a transmission clock fluctuates with respect to the cycle of a sampling clock for one bit on the reception side, a reception error occurs. To deal with this, every time sampling data is inverted in a reception data string, the sampling clock is re-synchronized. Furthermore, if there are a predetermined number of successive identical data, an inverted dummy bit is inserted for re-synchronization.
