The XMI
2.4.2.6 Node Specifier Field
The Node Specifier field is XMI D<15:0> L. During command cycle
interrupt transactions (INTR, IDENT, IVINTR), the Node Specifier field is
used to specify the source or destination of an interrupt. (See Figure 2–8.)
The relationship between bits in the Node Specifier field and the source or
destination of an interrupt transaction is shown in Figure 2–11.
The VAX 6000 uses nodes 1 through E.
