VMEbus Slave Address Translation Select Register 1

This register is the address translation select register for the first VMEbus
to local bus map decoder. The address translation select register value is
based on the segment size (the difference between the VMEbus starting
and ending addresses).

If the segment size is between the sizes shown in the table below, assume
the larger size.
