DM0 TO DM9: DIMMER DATA
This data controls the duty of the SG1 to SG56 segment 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 SG1 to SG56 segment output pins. The table lists the relationship between the dimmer data and
the dimmer value.
