Also note that when the general-purpose output port function is selected, the output pins and the display data will

have the correspondences listed in the tables below.

For example, if the output pin S4/P4 has the general-purpose output port function selected, it will output a high level

2. DR: 1/2-bias drive or 1/3-bias drive switching control data

This control data bit selects either 1/2-bias drive or 1/3-bias drive.

3. SC: Segments on/off control data

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

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 selects either normal mode or power-saving mode.
