Emergency
Messages

The next eight contiguous registers (registers 45375 through 45382) indicate the
presence or absence of newly received emergency messages for individual
modules on the island. Each bit represents a module:

z

A value of 1 in a given bit indicates that a new emergency message has been
queued for the associated module.

z

A value of 0 in a given bit indicates that no new emergency messages have been
received for the associated module since the last time the diagnostic buffer was
read.

The first two registers, shown below, provide the 32 bits that represent the module
locations available in a typical island configuration. The remaining six registers
(45377 through 45382) are available to support the island’s expansion capabilities:

15 14 13 12 11 10 9 8

7 6 5 4 3 2 1 0
