LP5864: Power management forum

Tool/software:

I design a circuit that drives LED with LP5864.

There are 46 LEDs in my circuit.

LP5864 can drive 4 scan lines with 18 current sinks.

But I want to drive 3 scan lines with 16 current sinks. 

so, I can drive 48 LEDs. (2 LEDs are not mounted.)

LP5864 can select scan line number by Max_Line_Num in registers.

In my case, Are 3 scan lines SW0, SW1, and SW2? 

(If I select 2 scan lines, Are 2 scan lines SW0 and SW1?)

and Is there any datasheet that includes detail of registers?

Best Regards,
