PURPOSE:To omit the mode for production of a special control signal and also to omit the need of hardware for settlement of the reception synchronization in the TDMA communication. CONSTITUTION:In a reception synchronization settlement state, a mode register 500 is set in a reception synchronization mode with the control signal received from a controller which controls a slave station and via a controller interface 423. A reception TDMA frame counter 481 sets a slot including the reference burst given from the controller and a frame number to the load input via a correction register 482. Then the counter 481 loads cyclically the same slot and frame number so as to repetitively output them. When a synchronizing signal is detected after reception of the reference burst, the counter 481 is loaded for settlement of the synchronization. At the same time, the settlement of synchronization is reported to the register 500. Thus the initial stage is complete for settlement of the reception synchronization, and the periodical loading operations are canceled. |
