Ultra Fast USB 2.0 Multi-Format Flash Media Controller
Datasheet
Note 7.8 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 10.1, “GPIO Usage (ROM Rev 0x00),” on page 28.
Note 7.9 The 3.3V supply should be at least at 75% of its operating condition before the 1.8V supply
is allowed to ramp up.
