METHOD FOR TRANSFERRING SERIAL DATA AND SERIAL DATA TRANSFER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for transferring serial data capable of rapidly transferring voice data and additive data even at the same number of routes as the case of transferring only conventional voice data with a simple constitution by reducing excess number of the routes and a serial data transfer system. SOLUTION: The method for transferring the serial data comprises the steps of generating a second control signal of repeating '0' and '1' and a control signal of repeating '0' and '1' at each falling edge of (n+m) times of the second control signal at a speed, in response to a transferring speed in a transmitter circuit 1, sequentially parallel-serial converting n-bit voice data 3 and m-bit additive data 4 in the order of the additive data and the voice data by an (n+m)-bit parallel-serial converter 11, according to the second control signal; generating a transfer signal for completing a final bit output of each voice data at an edge time of the first control signal; and outputting the second control signal, the first control signal and the transfer signal at the transmitter circuit 1 side.
