Digital Dimming Data Input [Function Mode: 4]
• ML9211 receives the digital dimming data when function mode 4 is selected.
• The output duty changes in the range of 0/1024 (0%) to 1016/1024 (99.2%) for each grid.
• The 10-bit digital dimming data is input from LSB.

Master Mode
Master Mode is selected when M/S pin is set at High level. The master mode operation is as
follows:
• The input levels of DIM IN, SYNC IN1 and SYNC IN2 are ignored, and these pins should be
connected to L-GND or V
.
DD
• Brightness is adjusted by the internal digital dimming circuit.
• The segment Latch1 to 3 corresponding to GRID1 to 3 are selected by the internal timing
generator.
