PURPOSE:To prevent a receiving data from loss due to no preparation of reception of a succeeding frame data by accumulating input data temporally, and at every detection of an end flag, repeating data sending to a data receiving part, stop and restart. CONSTITUTION:Received data 1 are accumulated in a data accumulating part 11, transferred to a data receiving part 14 by a high-speed timing signal 4 from a signal element timing generating part 13 and then sent to a data reception control part 15 by a signal 3. A flag sequence control part 12 monitors an output signal 6 from the accumulation part 11, and at the detection of the end flag of a frame, informs the stop of data sending and the stop of the signal 4 to the accumulation part 11 and the generation part 13 respectively and sends a false end flag to the receiving part 14 through an OR gate 16. The accumulation part 11 executes only the accumulation of the data. After completing the preparation of reception of the succeeding frame, the receiving part 14 informs the completion to the control part 12 through a control part 15 by a signal 10. Receiving said information, the control part 12 informs the completion to the accumulation part 11 and the generation part 13 to restart the signal 4 and transfer the accumulated data to the receiving part 14. |
