/// \unit
/// !Purpose
///
/// SCSI commands implementation.
///
/// !Usage
///
/// -# After a CBW is received from host, use SBC_GetCommandInformation to check
/// if the command is supported, and get the command length and type
/// information before processing it.
/// -# Then SBC_ProcessCommand can be used to handle a valid command, to
/// perform the command operations.
/// -# SBC_UpdateSenseData is used to update the sense data that will be sent
/// to host.
