Table 71 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.
