Abstract

PURPOSE: To easily restart operations even when a shift register is reset by obtaining a shift-in input through an EX-NOR gate to invert the output of an exclusive OR gate (EX-OR gate).
CONSTITUTION: While inputting the reset signals, flip-flops (1-1)-(1-5) are forcedly set in a reset state. In this case, the Q output of a flip-flop 4 is defined as an input to an EXNOR gate 3 and according to the state of the Q output, however, the EX-NOR gate 3 is operated as an AND gate 5 or an inverter. While the flip-flop 4 is set in the reset state, the EX-NOR gate 3 is operated as the inverter and as the result, the output of an EX-OR gate 2 in an 'L' state is inverted by the EX-NOR gate 3 and inputted to the flip-flop 1-1 as a data input in an 'H' state. Thus, operations are restarted.
