In VersaSafe multiplexer mode, the IC220SDL953 is always assigned one IC220SDL543
with the address xxxxx111 (xxxxx = island number). The IC220SDL953 and IC220SDL543
modules operate with a fixed parameterization.
To differentiate between VersaSafe and VersaSafe multiplexer mode, in VersaSafe mode
the address with "111" in the last three bits is not used. If an address with the format
xxxxx111 is specified in VersaSafe mode, the module enters the safe state.
Therefore, in VersaSafe multiplexer mode, the address xxxxx111 set on the IC220SDL543
corresponds to the setting for VersaSafe multiplexer mode and the island number on the
IC220SDL953.
