Abstract

PURPOSE:To make the data processing diverse, by detecting the level change of serial data and counting the number of times of detected data changes and supplying the counted result together with sampling data to a data processing means. CONSTITUTION:Serial data A from an input terminal 1 is inputted to a synchronizing signal detecting circuit 2 and a data latch circuit 4, and a synchronizing signal B is outputted from the circuit 2, and a sampling signal C is outputted from a sampling signal generating circuit 3, and sampling data D is outputted from the circuit 4. The rise and the fall of data A are detected by rise and fall detecting circuits 8 and 9, respectively, and level change points of the signal A are counted in a counter circuit 11 through an OR circuit 10. Each time the signal B disappears and data A is sampled by the signal C, the circuit 11 is cleared; and the counted result of the circuit 11 is applied to a serial-parallel converting and data processing part 5, to which signals C and D are inputted, through a count latch circuit 12, thus making the data processing diverse.
