Abstract
A controller for effecting a serial data communication and a system including the controller in a transmitting side and/or a receiving side thereof. The controller includes a unit for serially storing data, a unit for arbitrarily setting a bit length of data to be an object of the serial data communication, a unit for controlling a first clock to synchronize with the serial data in a serial data communication duration, and controlling a second clock to synchronize with the serial data in a duration, and a unit for indicating a permission or inhibition of the serial data communication according to whether the counted value of the first clock is within or out of a value defined by the arbitrarily set bit length. By taking data of the arbitrarily set bit length out of the serial data stored in the memory unit when the serial data communication duration is indicated, to effect the serial data communication, and inhibiting the serial data communication when the duration is indicated, it is possible to effect a serial data communication of arbitrary bit length and thus reduce the communication time.
