Abstract
PURPOSE: To prevent reading of ineffective clocks owing to noise, etc. by outputting block signals after counting of a specified number since input signal was applied.
CONSTITUTION: When the input signal having been read is applied to terminal IT 1, a counter CNT which counts a specified number through an OR gate OR 1, NOR gate NOR 1 starts counting. Each time when this counter CNT counts a specified number, an FF 16 is inverted by the NAND output from a NAND gate ND 2, by which an AND gate AG 1 is opened. This causes the counter CNT to be reset and the inversion output of the FF to become a block signal, thus reading of the data is accomplished. Hence, no block signals are produced at the inputting of the read signal owing to noise, etc. of the nonblock part and reading of the effective block is thus prevented. A block which has missing of signals of less than specified number owing to segmenting of the data block by the burst of the clock signal may also be read in the similar manner.
