Output leakage is measured with the current pins in high impedance.
See Appendix A for USB DC electrical characteristics.
The Maximum power dissipation parameters of the package should not be exceeded
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
