<p>PURPOSE:To realize a bi-directional serial interface through simple device configuration, and to lighten the burden of processing by providing the devices of both sides respectively with a parallel/serial converter, a serial/parallel converter, and a control means. CONSTITUTION:Data transfer clock generating means 11, 14a, the parallel/serial converters 14b, 24e, the serial/parallel converters 14c, 24d, and the control means 11, 21 are provided. Then, serial data outputted from the first parallel/serial converter 14b is inputted to the second serial/parallel converter 24d, and the serial data outputted from the second parallel/serial converter 24e is inputted to the first serial/parallel converter 14c. Thus, the bi-directional serial interface can be realized through the simple device configuration, and by executing the input/output of the data at a fixed interval of time, the burden of the processing can be lightened.</p> |
