Ultra Fast USB 2.0 Multi-Slot Flash Media Controller Datasheet Chapter 5 Pin Descriptions This section provides a detailed description of each signal. The signals are arranged in functional groups according to their associated interface. The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “n” is not present before the signal name, the signal is asserted at the high voltage level.
