Abstract
PURPOSE:To shorten the program processing time of a data processor by sending data in series while inspecting their variation, one by one, by a 1st shift register and an exclusive OR gate, and interrupting a data processor when a reception- side detecting and holding circuit detects a dissident bit in the data. CONSTITUTION:Parallel data 8 which are read in a parallel-series (PS) shift register 9 previously with data transfer timing 5 are outputted, one by one, to the EXOR gate 21 and S shift register 20. The data register 12 reads in the data of an SP shift register 11 with a next data transfer start signal 4 and a DFF 23 reads in the dissident bit detection result of a JKFF 22 and interrupts the data processor 15. The data processor 15 outputs a gate signal to the data register 12, reads in parallel data 14 outputted by the data register 12, and performs data detection processing for detecting variation data. The data processor, therefore, need not read new data unnecessarily and the program processing time is shortened.
