Those cards support capacity larger than 2TB and up to including 128TB. Thus, the address range of the card expands beyond the 32-bit command argument. To that end, a new command - CMD22 is defined, to carry the extra 6-bit upper part of the 38-bit block address that enable access to 128TB memory space. SDUC capacity is agnostic to the interface mode: UHS-I and UHS-II – Same as SDXC. The spec defines several extensions/modifications to the current SDXC cards, which we address in patches 1 - 10. Otherwise requirements are out-of-scope of this change. Specifically, CMDQ (CMD44+CMD45), and Extension for Video Speed Class (CMD20). First publication of SDUC was in [1]. This series was developed and tested separately from [1] and does not borrow from it.
