Title:
DATA TRANSFER SYSTEM
Document Type and Number:
Japanese Patent JPH1174856
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the number of signal lines connecting data transferring devices, and to reduce package space and cost by multiplexing a data signal and a state control signal into serial data, and transferring it, and demultiplexing the serial data into the state control signal and the data signal by using the state control signal transferred separately from the serial data, and reproducing. SOLUTION: A multiplex converting circuit 8 of a data transferring device 1 at a transmitter side converts a control signal from a synchronizing circuit 6 and a data signal from a transmission register 7 into one bit serial data, and outputs it. A demultiplex converting circuit 11 of a data transferring device 2 at a receiver side demultiplexes the serial data inputted from a data line 3 into the first half and the second half, and distributes the data to a control register 12 and a reception register 13. The serial data are converted into parallel data, and the control signal and the data signal are restored. This data transfer control is operated through a CLK signal line 4 and an SYNC signal line 5 being a transfer control line 10.
