by setting the R/L pin.
Used to create the sampling signals corresponding to each output pin based on the
sampling start signals transferred by the bi-directional shift register.
Used to set the form of the video signals to be sent to the sample and hold circuits.
Used to sample the video signals input from the mode setting circuit at the timing of the
sampling signals and hold the sampling data until the next sampling operation.
