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. SP: Normal mode/sleep mode control data
6. DT1, DT2: Display technique setting data
Note: COMn (n = 9 or 10): Common outputs
