伝送装置のリセツト回路。 In a data transmission device that serially transmits and receives data by adding a start bit and a stop bit to one unit of data consisting of multiple bits, a signal that is longer than one unit of data length and has the same signal level as the start bit is sent to the transmission line. Determine the signal level of one unit of data received from the first circuit to send and the reception line, and if it is the same as the signal level of the start bit and longer than the data length of one unit, reset the entire data transmission device. 1. A reset circuit for a data transmission device, comprising: a second circuit that performs the reset operation.
