Display digit data

DG1 DG2 DG3 DG4 DG5 DG6 DG7 DG8 DG9 DG10 DG11 DG12

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

Common and segment output pin states

0

Output of LCD drive waveforms

1

Fixed at the VSS level (all segments off)

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

Mode

0

Normal mode

Power saving mode

1

(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.)
