Note 5-1 Output leakage is measured with the current pins in high impedance.
Note 5-2 See Appendix A for USB DC electrical characteristics.
Note 5-3 The Maximum power dissipation parameters of the package should not be exceeded
Note 5-4 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
Table 7-1, “GPIO Usage (ROM Rev -11),” on page 20.
