PURPOSE:To make it possible to measure any bit pattern of transmission data, by obtaining the reference data of a data transmitter by delaying the transmission data by a first-in first-out register. CONSTITUTION:Sending data SD to transmission line 7 are fetched into first-in first-out register 26, and compared 5 bit by bit with reception data from a transmission line which corresponds to its output, thereby counting 6 dissident bits. Then, a bit pattern composed only of the 1st binary signal is transmitted as the transmission data, and the transmission of a bit sequence containing the 2nd binary signal is started; when the 2nd binary signal appears in the output of register 26, the outputting of data from register 26 is interrupted and when the 2nd binary signal appears in the reception data, the outputting of data from register 26 is restarted. |
