7 / 18 page Control Data • S0, S1: Sleep control data This control data controls switching between sleep mode and normal mode, and also sets the states of the KS1 to KS6 key scan output pins in key scan standby mode. • DM0 to DM9: Dimmer data This data controls the duty of the G1, G2 digit output pins. This data forms a 10-bit binary value in which D0 is the LSB. The brightness of the display can be controlled by adjusting the duty of the G1, G2 digit output pins. The table lists the relationship between the dimmer data and the dimmer value. t3 and t4: See figure 5. Relationship between the Display Data (D1 to D82) and the Segment Output Pins As an example, the table below lists the operation of the S11 segment output pin.
