Anode Dimming Data Input [Function Mode: 4]

N ML9213 receives the anode dimming data when function mode 4 is selected.

N The output duty changes in the range of 0/1024 (0%) to 1016/1024 (99.2%) for each grid.

N The 10-bit anode 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:

N Input to DIM IN, SYNC IN1 and SYNC IN2 is ignored, and these pins should be connected to L-GND or V

N The pulse width of SEG1 to SEG56 is controlled by the internal digital dimming circuit.

N The segment data corresponding to GRID1 to 3 is selected by the internal timing generator.
