4. SC: Segment on/off control data

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

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.

5. SP: Normal mode/sleep mode control data

This control data bit controls the normal mode and sleep mode.

The common and segment pins go to the VLCD4 level and the oscillator on the OSC pin is stopped (although it operates during key

scan operations) to reduce current drain. Note that the states of the general-purpose output ports P1 to P4 are set by PC1 to PC4 in

the control data during sleep mode as well as normal mode.

6. DT1, DT2: Display technique setting data

These control data bits set the display technique.
