(2) Window data: DATA OUT phase (initiator Æ target)
Window data specifies the details of a window. Window data contains a head and
one or more window descriptor block. Each window descriptor block specifies the
attributes of a window (size, position, scan mode, etc.).
If a target receives the SET WINDOW command when it already has window data,
the target discards all of the current window data and validates the newly received
data.
