PURPOSE:To flexibly correspond to the difference of status signal forms and to simplify the constitution for miniaturization and cost reduction by performing processing for establishing the multi-frame synchronizing and taking out a status signal with the use of the same general data processing circuit. CONSTITUTION:A control circuit 13 judges a synchronizing status by sampling the synchronizing decision bit of the address of a memory 11. A counting/latch circuit 6 and a selection circuit 7 or the like fetch multi-frame synchronizing bits as a sample and a comparator circuit 5 or the like establishes the synchronization of multi-frame. The same general data processing circuit which is composed of the above-mentioned circuits stabilizes signals by rearranging status signals with the use of a status signal line conversion circuit 4 to be successively stored in the memory 11. Thus, the miniaturization and cost reduction can be attained by flexibly corresponding to each status signal form and simplifying the circuitry. |
