DESCRIPTION
Set the LSB weight of the linear current setting of the open-drain
driver. [1:0]=00 for 0.4mA, 01 for 0.8mA, 10 for 1.2mA, 11 for
1.6mA.

For linear duty setting option, the LSB weight is 0.4% for code
0x00 to 0xFE, which is 0% to 99.2% of duty. The code 0xFF is
forced for 100% duty.
For the non-linear duty setting option, refer to the table of NON-
LINEAR DUTY SETTING for code to duty cross.
