This register is the attribute register for the third local bus to
VMEbus bus map decoder.
AM These bits define the VMEbus address modifier
codes the VMEbus master uses for the segment
defined by map decoder 3. Because the local bus to
VMEbus interface does not support block transfers,
the block transfer address modifier codes should not
be used.
WP When this bit is high, write posting is enabled to the
segment defined by map decoder 3. When this bit is
low, write posting is disabled to the segment
defined by map decoder 3.
When this bit is high, D16 data transfers are
D16
performed to the segment defined by map decoder
3. When this bit is low, D32 data transfers are per-
formed to the segment defined by map decoder 3.
