    Description: This file provides the external interface
    to the events that can be published/processed in the
    system.  It is specifically by itself (and nothing
    else should be defined in here) so that both .c and
    .S (assembly) files can include this file without
    a problem.

    definitions were never translated back....doesn't make a
