Description: On get each bit indicates whether the corresponding attribute is configured or unconfigured: 0 = The attribute is configured (i.e. the configured value is the operational value). 1 = The attribute is unconfigured (i.e. the operational value is inherited from the a higher level which could be the default value).

Getting the attribute value itself always returns the operational value of that attribute regardless of whether the attribute is configured or unconfigured.

On write each bit indicates wheter or not the corresponding attribute should be set to the unconfigured state: 0 = No operation (i.e. do not change the state of the attribute). 1 = Set the attribute to the unconfigured state.

Setting an attribute to a value has the automatic side-effect of setting the bit with the same name to zero.
