Abstract

PURPOSE:To ensure the assured transfer of information with no interruption although the working speed of an external controller is not so high, by transmitting the parallel information given from a microcomputer, etc. after converting it into the series information. CONSTITUTION:In case the information of transfer is sent to a shift register SH at times t3-t5, a line (b) is set at logic value ''0''. Thus the clock pulse, although it arrives at a line (a), is inhibited for its passing by an AND circuit AND. The output line (f) is set at logic value ''0'', and the load pulse transmitted to a line (c) becomes effective. When the line (b) is reset at logic ''1'' with the resetting of a flip-flop FF, the circuit AND releases the inhibition of the clock pulse. Thus the clock pulse emerges on the line (f). The first bit of the stored information of the register SH is transmitted at the fall of the pulse, i.e., the clock on a line (e).
