PURPOSE:To provide a data transmitting/receiving device which can transmit and receive more than the quantity of data that can be stored in a transmitted data storage area of a RAM. CONSTITUTION:A table is prepared to show the addresses of RAMs storing the control data and the data transmitting sequence for each group of many control data. In a data transmission mode, the transmitted data consisting of the control data DATA and a schedule counter COUNT chowing the transmitting sequence in the relevant data group prepared for each of data groups (1)-(N) and stored in sequence in a transmitted data storage area of the RAM. Furthermore the transmitted data are changed for each group and each data group. Therefore the transmitted data storage area of the RAM is used every two bytes and for each data group. Thus a large quantity of data can be transmitted and received with out being limitted by the capacity of the transmitting data storage area of the RAM. |
