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.
