Abstract: PURPOSE:To generate a received clock of the same reception frequency as a transmission frequency by analyzing the transmission frequency from transmit data. CONSTITUTION:An edge detecting circuit 2 detects change points of serial data IN and a counter 3 measures intervals of the change points. Further, the counter 3 measures the interval of data to the 1st bit of the serial data IN and writes them in a 1st register 5. Similarly, the interval of data to the 2nd bit is written in a 2nd register 8. A comparing circuit 9 compares the contents of both the registers 5 and 8 with each other and decides that the bit width of the received data can be measured when the contents match each other to output a coincidence signal (h) to a central processing unit 6, thus initiating an interruption. Further, the contents of the 2nd register 8 are counted by a baud rate generating circuit 11 to generate the received clock of the same frequency as the transmission frequency. When the contents of both the registers 5 and 8 are different, the measurement is repeated until they match each other.
