Bits 0, 1: NODE_LOC [0:1]
These bits determine the location of the NODE_ID parameter in the header
(the location is specified in bytes excluding preamble). The location should be
fixed for all of different kinds of packets transferred by the system. NODE_ID
must never be set to be smaller than NET_ID, if both filters are enabled.
