Table 100 Configure Stream Command (51h)
The Configure Stream command specifies the operating parameters of an individual stream. A Configure Stream
command may be issued for each stream that is to be added or removed from the current operating configuration. If
A/R = 1 and the specified ID is already valid at the device, the new parameters shall replace the old parameters,
unless Command Abort is returned (see abort conditions for Error Register). In this case the old parameters for the
specified Stream ID shall remain in effect.
Abort conditions for Error register are the following.
The device does not support the Streaming Feature Set.
A/R is cleared to zero and the Feature field contains a Stream ID that has not been sent in a previous
CONFIGURE STREAM command.
