UHS-II Pin Layout

A new pin layout was introduced to support the UHS-II bus interface. The new second-row pins on the full-size SD memory card and microSD memory card are used for the UHS-II signals. The first-row pins are used for the normal speed, high speed and UHS-I bus interface signals to provide interoperability with existing non-UHS-II host devices.
