M0:

Digital/analog dimmer selection data

M0 = 0 ....................................Digital dimmer

M0 = 1 ....................................Analog dimmer

DM0 to DM9: Dimmer data

This data controls the duty of the G1 and G2 digit output pins when the digital dimmer is selected.

This data consists of 10 bits, of which DM0 is the LSB. Note that display intensity can be adjusted by

controlling the duty of the G1 and G2 digit output pins. (The DM0 to DM9 dimmer data is ignored

when the analog dimmer is selected.)

SD1 to SD38: Display data

SD1 to SD19...........................Display data for the G1 digit output pin

SD20 to SD38.........................Display data for the G2 digit output pin

SDn (n = 1 to 38) = 1..............Display on

SDn (n = 1 to 38) = 0..............Display off

T0:

Test data

The T0 bit must be set to 0.
