Common Services
Object Specific Services
The table below lists the parameters for the Get_Attributes_Scattered
and Set_Attributes_Scattered object-specific service:
26 Not Writable While IO Active This parameter cannot be written if the I/O data being exchanged between the
Host and the peripheral is valid.
27 Command Parameter This parameter commands the drive to take an action, such as “Reset Defaults”
or “Autotune,” and then returns to a value of zero. Offline software tools will not
allow setting this parameter to anything other than a value of zero. If an offline
file contains a Command Parameter with a non-zero value, the offline software
tool will change the value to zero. Note that command parameters cannot have
values that do not return to zero.
28 Current Value Is Default This bit identifies a parameter that will not change if a “Reset Defaults” is
commanded. For example, if a drive contains a Language parameter that is set
to German, setting defaults will leave the parameter set to German. Likewise, if
the parameter is set to French, setting defaults will leave the parameter set to
French.
29 Use Zero Text If the “Disallow Zero” bit is set, this bit must be cleared. If the “Disallow Zero” bit
is cleared, then:
0 = Use Disabled Text parameter class attribute.
1 = Use Zero Text parameter instance attribute.
30-31 Reserved Reserved
