For example, if DG1 to DG6 are 1, and DG7 to DG12 are 0, then display digits 1 to 6 will be turned on, and display digits 7 to 12
will be turned off (blanked).
10.2.3. SC: Controls the common and segment output pins
SC
0
Common and segment output pin states
Output of LCD drive waveforms
Fixed at the VSS level (all segments off)
1
NOTE: When SC is 1, the S1 to S60 and COM1 to COM10 output pins are set to the VSS level, regardless of the M, A, and DG1 to DG12
data.
10.2.4. BU: Controls the normal mode and power saving mode
BU
0
Mode
Normal mode
Power saving mode
(In this mode, the OSCI and OSCO pins oscillator is stopped, and the common and segment pins are set to the VSS level. In
this mode, instructions other than the “display on/off control” instruction cannot be executed. Thus applications must set the LSI
to normal mode before executing any of the other instructions.)
