These bits define the VMEbus address modifier codes that
the VMEbus master uses for the segment defined by map
decoder 2. Since the local-bus-to-VMEbus interface does
not support block transfers, the block transfer address
modifier codes should not be used.
When this bit is high, write posting is enabled to the
segment defined by map decoder 2. When this bit is low,
write posting is disabled to the segment defined by map
decoder 2.
When this bit is high, D16 data transfers are performed to
the segment defined by map decoder 2. When this bit is
low, D32 data transfers are performed to the segment
defined by map decoder 2.
