Note: There are 16 power levels, whereas the first 8 levels are registers that can be configured by users.

During operation, a change in one of the PG pins will change PD69104B1/F’s total power budget and

may result in turning off ports. The power level can be set either by PS_PG0 to PS_PG3 pins or by the

host through communication.
