AX51: ERRORS ASSEMBLING XBANKING.A51

Information in this article applies to:

When creating a project that uses XBANKING, the following error may be received when you assemble the XBANKING.A51 file using the AX51 assembler.

000000                  106+1   ?C?CLDXPTR:     LOAD_BANK
*** ERROR #A45 IN 107 (XBANKING.A51, LINE 106): UNDEFINED SYMBOL

The error indicates that there is an undefined symbol in the LOAD_BANK macro.

This error is caused by the registers DPL and DPH that are undefined by the AX51 assembler.

Define the DPL and DPH registers prior to using the LOAD_BANK macro. This will solve this problem. For example:

B       DATA 0F0H       ; SFR Address
DPL     DATA 082H
DPH     DATA 083H
