A1054: References on non-absolute objects are not allowed when options -FA1 or -FA2 are enabled

[ERROR]

Description

A reference to a relocatable object has been detected during generation of an absolute file by the assembler.

Example
           XREF extData

  DataSec: SECTION

  data1:   DS.W 1

           ORG $800

  entry:

           DC.W extData

           DC.W data1+2
  
Tips

When you are generating an absolute file, your application should be encoded in a single source file, and should only contain any relocatable symbol. So in order to avoid this message, define all your section as absolute section and remove all XREF directives from your source file.

Example
           ORG $B00

  data1:   DS.W 1

           ORG $800

  entry:

           DC.W data1+2
