AP1000 PMS SD application-specific callback procedures are implemented to provide additional display
application functionality which is not available from the standard Photon display components or in the
generic Common Q FPD library described in Section 4.4. The subsections of Section 5.3 describe the
individual callback procedures configured into the Photon display application to provide the functionality
described in Section 5.2.
Since many of the callbacks described within this section require a unique identifier for dynamic
processing, a sequential numbering scheme has been defined for each display within the application.
Table 5.3-1 defines a unique number for each display. Any future references to a display screen number
or version ID are a direct reference to this table.
