Abstract
Disclosed is a signal transmitting and receiving apparatus for transmitting and receiving parallel-by-word data signals, converting the parallel-by-word data signal to serial-by-word data signal, and transmitting the serial-by-word data signal to control units connected in a multi-drop connection configuration or receiving the signals transmitted from the control units. An external control mode and an internal control mode in receiving the parallel-by-word data signal, a simulation mode, and the prevention of competing status between a write timing of the parallel-by-word data to a buffer memory and a read timing of the data for converting it to serial-by-word data are described.
