6. SC: Segment on/off switching control data
This control data bit controls the on/off state of the segments.
SC
Display state
0
On
1
Off
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.
7. BU: Normal mode/power-saving mode switching control data
This control data bit selects either normal mode or power-saving mode.
BU
Mode
0
Normal Mode
1
Power-saving Mode
Power-saving mode status: S1/P1/G1 to S6/P6/G6 = active only General Purpose output
S7 to S54 = low(VSS)
COM1 to COM4 = low(VSS)
Shut off current to the LCD drive bias voltage generation circuit
Stop the Internal oscillation circuit
However , serial data transfer is possible when Power-saving mode.
8. PG1, PG2, PG3, PG4, PG5, PG6: PWM/General Purpose output switching control data
This control data bit select either PWM output or General Purpose output of Sx/Px/Gx pins.(x=1～6)
PGx(x=1 6)
Mode
0
PWM output
1
General Purpose output
<Note: PWM<->GPO Changing function>
Normal behavior of changing GPO to PWM is below.
- PWM operation is started by command import timing of DD: 01 during GPO ---> PWM change.
- Please take care of reflect timing of new duty setting of DD: 10, DD: 11 is from the next PWM.

(PWM waveform in new duty)
In order to avoid this operation, please input commands reversely as below.
