DATA COMMUNICATION EQUIPMENT
Document Type and Number:
Japanese Patent JPS63240661
Kind Code:
A
Abstract:
PURPOSE:To transmit data to an optional address of a reception memory from the transmission side by mixing an address signal into a data signal train sent from the transmission side. CONSTITUTION:A ready signal generator 25 transmits a reception ready signal to an enable signal generator 26 set at the transmission side by an instruction given from a receiving CPU 12. Then a receiving CPU 11 produces an address to a transmission memory 13 via an address generator 17 and gives an access to the data. Thus the data and the address are latched by an FF 21 and an FF 22 respectively and transmitted alternately by the signal given from a transmission clock generator 18. Then the address clock signal is separated from the data clock signal via a transmission address/data switch 19 and a reception clock generator 20. These separated signals are written into a reception memory 14. Thus it is possible to store data into an optional address of the memory 14 from the transmission side regardless of the address control of the reception side.
