Abstract
A data shift control circuit for a shift register in response to a logic operation command code is disclosed. The shift register includes a first register and a second register and the logic operation command code includes a first portion and a second portion. The circuit includes a first decoder for decoding the first portion to transmit a move signal; a second decoder for decoding the second portion to transmit a control signal; a control signal channel, electrically connected to the first register and the second register, for allowing the first register and the second register to receive the control signal and for allowing the shift register to execute a first action; and a move signal channel, electrically connected to all registers of the shift register for allowing the all registers to receive the move signal and for allowing the move register to execute a second action.
