4. SC : Segment on/off control data
However, note that when the segments are turned off by setting SC to 1, the segments are turned off by outputting segment off waveforms from the segment
output pins.
5. DR : 1/2 bias or 1/3 bias drive selection data
Display Data and Output Pin Correspondence
Note: This is for the case where the output pins S1/P1 to S4/P4, KS1/S24 and KS2/S25 are selected for use as segment outputs.
For example, the table below lists the segment output states for the S11 output pin.

Output pin
This control data bit controls the on/off state of the segments.
This control data bit switches between LCD 1/2 bias or 1/3 bias drive.
