This figure shows the first 2 registers, which provide the 32 bits that represent each
of the 32 (maximum) module locations available in a typical island configuration.
(The remaining 6 registers, 45361 through 45366, are reserved and not used.)
Node Assembly
The next 8 contiguous registers (45367 through 45374) indicate the presence or
absence of configured modules in locations on the island bus. 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 one of the 32 modules:
z A value of 1 in a given bit indicates that the configured module is not present.
z A value of 0 indicates that the correct module is present in its configured location,
or that the location has not been configured.
