(1)

This parameter defines the minimum data valid window required by the host, where any data valid window presented to the host

greater than this value ensures the host is able to capture valid data. The value defined by this parameter is smaller than the smallest

possible data valid window defined for any eMMC device operating in HS200 mode.
