This is more some kind of bus/device error not related to a 802.15.4 operation, and in this case we should use the SYSTEM_ERROR which 802.15.4 says it can be used for a kind of "user specific error"? I mean it is not user specific but 802.15.4 spec will never reference it to make some special handling if it occurs... just "something failed". - Alex
