Geographical Address Switch (S3)

The TSi148 VMEbus Status register provides the VMEbus geographical address of the
MVME3100. This switch reflects the inverted states of the geographical address signals.
Applications not using the 5-row backplane can use the geographical address switch to assign
a geographical address.
