Abstract

PURPOSE:To freely turn on an electric power supply of a peripheral equipment and to prevent a receiving error, by monitoring a state of transmission data on the bus in case when the electric power supply of the peripheral equipment has been turned on, and providing the data from a position of a start bit. CONSTITUTION:When an electric power supply of a peripheral equipment is turned on when serial data is transmitted, a clock counter 4 and a bit counter 6 are cleared, and a data flip-flop 3 is reset. Subsequently, in the serial data transmission line, a synchronizing flip-flop 7 is set between data and data, and by its output, a receiving data gate 2 is opened, therefore, a transmitting and receiving circuit 8 is capable of receiving the receive data from the start bit, and the data is received in a normal state.
