The next eight contiguous registers (registers 45367 through 45374) indicate the
presence or absence of configured modules in locations on the island bus. This
information is stored in Flash memory. At start up, the actual locations of the
modules on the island are validated by comparing them to the configured locations
stored in memory. Each bit represents a module:
z A value of 1 in a given bit indicates either that the configured module is not
present or that the location has not been configured.
z A value of 0 indicates that the correct module is present in its configured location.
The first two registers, shown below, provide the 32 bits that represent the module
locations in a typical island configuration. The remaining six registers (45369
through 45374) are available to support island expansion capabilities.
