• Manufacturer Part Number: lc75848t
• Description: 1/8 To 1/10 Duty General-purpose Lcd Display Drivers
• Manufacturer: Sanyo Semiconductor Corporation

3. 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.
4. BU: Normal mode/power saving mode control data
5. FC: Data that sets the frame frequency of the common and segment output waveforms
6. DT1, DT2: Display technique setting data
Notes: Sn (n = 94 or 95): Segment outputs

This control data bit controls the on/off state of the segments.
This control data bit controls the normal mode and power saving mode.
This control data sets the frame frequency of the common and segment output waveforms.
This control data bits set the display technique.
