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.
