3. SC: Segment on/off control data

This control data bit controls the on/off state of the segments.

SC

Display state

0

On

1

Off

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

This control data bit controls the normal mode and power saving mode.

BU

Mode

0

Normal mode

Power-saving mode.

1

The common and segment pins go to the VLCD4 level and the oscillator on the OSC pin is stopped. Note that the

states of the general-purpose output ports P1 to P4 are set by PC1 to PC4 in the control data during power saving

mode as well as normal mode.

5. DT1, DT2: Display technique setting data

This control data bits set the display technique.
