With MS connected to GND, it represents it is in slave mode, it will treat all the DIN data as display data

and will be sent to ML2002’s display shift register directly through DIN and DCLK.

To Load display data onto the screen, LAI need to be high, then a rising edge of DCLK would load the

display, the LAI need to keep low again.

There are 48 Segments in Static Mode, and 96 Segments in 1/2 Duty Mode with 1/2 Bias. The display

data should be input in reverse order, for static it’s starting from SEG48, SEG47… SEG2 to SEG1, for

1/2 duty it’s starting from SEG48-COMB, SEG48-COMA … SEG1-COMB to SEG1-COMA for proper

display of data. When updating the display, it will require inputting 48 Segments in Static Mode and 96

Segments in 1/2 Duty Mode.
