Appendix A.4.1. Accessing Priority Array information
The Priority Array table and its "In_Use" (or Not Relinquished) state are stored internally to every Map Descriptor, and cannot be accessed directly. The information can
be accessed indirectly by specifying the following Data Arrays which will maintain an exact copy of the Priority Array Table for the Map Descriptor.
Section Title
Map_Descriptors
Column Title Function
Name of Data Array where the Priority Array Table will be stored. Location 0 is the Relinquish Default value and
DA_Pri_Array
locations 1 to 16 the different entries of the Priority Array Table.
DA_Pri_Array_Offset* Starting location in Data Array.
Name of Data Array that indicates if a particular Priority Value is in use. Location 0 indicates whether the Relinquish
DA_Pri_In_Use
Default has been set and locations 1 to 16 indicate whether the index is in use (1), or Relinquished (0).
DA_Pri_In_Use_Offset* Starting location in Data Array.
// Analog Output Map_Descriptor for testing Priority Arrays
