![]() Into the flip-flop chain is to load the data one bit each clock cycle using theĪlso have parallel inputs that can be used to load all n bits in one clock cycle. Provision for shifting only in one direction, but some have a control input thatĪllows either left or right shifting to be specified at each clock. ![]() Register can obviously be used for left shifts simply by reversing the sense of Shifted off the other end is lost unless it is saved externally. The new bit to be shifted into one end must be specified, and the bit 1 shows a simple shift register configuration. Receive a common clock pulse which causes the shift from one stage to the next. Logical configuration of a shift register consists of a chain of flip-flopsĬonnected in cascade, with the output of one flip-flop connected to the input of Shift register is an n-bit register with provision for shifting its stored data
