2. DR: 1/2-bias drive or 1/3-bias drive switching control data
3. SC: Segments on/off control data
4. BU: Normal mode/power-saving mode control data
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
(V
This control data bit selects either 1/2-bias drive or 1/3-bias drive.
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.
This control data bit selects either normal mode or power-saving mode.

Power saving mode (The OSC pin oscillator is stopped, and the common and segment output pins go to the VSS level. However, the
S1/P1 to S8/P8 output pins that are set to be general-purpose output ports by the control data P0 to P3 can be used as general-
purpose output ports.)
