Abstract

PURPOSE:To ensure an easy transmission for the serial or parallel data by transferring the data given from the memory to the serial data transmission circuit via the connection circuit or to the parallel data transmission circuit after converting the data into the parallel data. CONSTITUTION:Integrated circuit 8 consists of register 1, parallel-serial converter 2, serial-parallel converter 3 and register 4 each. And converters 2 and 3 are connected to connection circuit 7, and at the same time transmission circuits 5 and 6 are connected to circuit 7 and register 4 respectively. Thus the transmission data drawn out of memory 10 is transferred to register 1 in circuit 8 to be stored temporarily and then transferred to converter 2 to be converted into the serial data. This serial data is transferred to circuit 5 or transmitted 6 after converted 3 into the paralles data. As a result, the transmission can be facilitated for the serial or parallel data by just switching connection circuit 7.
