• 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.
