Note 1:
This command is not a standard PC Card ATA command but provides additional functionality.
Definitions: FR = Features Register, SC = Sector Count Register, SN = Sector Number Register, CY = Cylinder
Registers, DH = Card/Drive/Head Register, LBA = Logical Block Address Mode Supported (see
command descriptions for use).
Y - The register contains a valid parameter for this command. For the Drive/Head Register Y means both
the SDP3B FlashDisk and head parameters are used; D - only the SDP3B FlashDisk parameter is valid
and not the head parameter.
