R/W 0h Adjust current from current source.
Output currents may be combined to get desired total current.
0h = No current connected
1h = 0P25U : 0.25 µA
2h = 0P5U : 0.5 µA
4h = 1P0U : 1.0 µA
8h = 2P0U : 2.0 µA
10h = 4P5U : 4.5 µA
20h = 11P75U : 11.75 µA
R/W 0h
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
