memory locations differentiated from other such sets in VXI/
VMEbus systems by six addressing lines known as address modifiers.
n
is the number of address lines required to uniquely specify a byte
location in a given space. Valid numbers for
n
are 16, 24, and 32. In
VME/VXI, because there are six address modifiers, there are 64
