Abstract: PURPOSE:To allow a digital data public communication network to utilize even a start-stop data by providing a start-stop data correction circuit which adds a stop bit to a received data to adjust the reception data to a reception data processing unit and a reception buffer which adjusts a timewise deviation of transmission and reception due to 1-bit insertion to the adjustment circuit. CONSTITUTION:A length of a start-stop data of a received data is set by a start-stop data set latch section B and latched. The start-stop data representing also its length is inputted to a stop bit control section C, in which the data is counted up from a start bit and its stop bit is monitored and whether or not the data is at an H level or an L level at the stop bit is discriminated and the data is received as it is when the level is an H level and the reception of one clock by a stop adjustment clock generating section E is stopped when the level is an L level and an H level is inserted by one clock by a start-stop correction circuit F. In this case, a time deviation is caused between the reception serial data H and the reception data I by the insertion of one bit, but the deviation is absorbed by a reception buffer G. Thus, the start-stop system is utilized by the digital data public communication network.
