Output leakage is measured with the current pins in high impedance.
See The USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics
RBIAS is a 3.3 V tolerant analog pin.
Output current range is controlled by program software, software disables FET during short
circuit condition.
The assignment of each Integrated Card Power FET to a designated Card Connector is
controlled by both firmware and the specific board implementation. Firmware will default to
the settings listed in

The 3.3 V supply should be at least at 75% of its operating condition before the 1.8 V
supply is allowed to ramp up.
