===== I2C =====
Looks like ncp4200 i2c address could be floating depending
on the system. List all possibilities here (0x60 - 0x63).

===== frequency =====
The clock frequency of the NCP4200 is set with an
external resistor connected from the RT pin to ground. The
frequency follows the graph in Figure 3. To determine the
frequency per phase, the clock is divided by the number of
phases in use. If all phases are in use, divide by 4. If 2 phases
are in use then divide by 2.

===== decoupling =====
