The IVINTR Destination field determines which nodes on the XMI will
be targeted by the DWMBB when it issues an Implied Vector Interrupt
transaction. Each of the 16 bits corresponds to one of the 16 XMI
nodes (only 14 nodes are used in the VAX 6000 platform). When a bit
is set, the selected node will be the target. For example, if bit <12>
becomes set, then XMI node 12 is the node that the DWMBB selects to
participate in the IVINTR transaction. Any number of bits can be set.
