Shift direction

The input signals OE1, 2, 3 and the shift data control the value of the outputs (X1 till X240). Their value can be either VGG or

VEE.

The signal LR controls the shift direction of the shift register. The shift register takes its value from one of the input/output

pins DIO at the rising edge of the clock FX and shifts the value to the other input/output pin DIO where it is presented at the

falling edge of FX.
