Detailed Description

Purpose

SCSI commands implementation.

section Usage

1. 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.
2. Then SBC_ProcessCommand can be used to handle a valid command, to perform the command operations.
3. SBC_UpdateSenseData is used to update the sense data that will be sent to host.
