The current DAC has three possible current ranges that can be selected using the 
DacRange[1:0] bits in the CurrDacCtrl register. The DAC range selection table is shown in 

.

         

By changing LSB current value, all steps will change following this relation:

I

step

(N) = N * I

LSB

where N is the value of DacValue[5:0] bits.
