12.3.15 A2305: Illegal Redefinition of Instruction or Directive Name
Type: Error
Description: An assembly directive or an HC12 instruction name has been
used as a macro name. This is not allowed to avoid any
ambiguity when the symbol name is encountered. The macro
assembler cannot detect if the symbol refers to the macro or the
instruction.
Example:
ADDD: MACRO
LDD \1
ADD \2
STD \1
ENDM
Tip: Change the name of the macro to an unused identifier.
Example:
ADDM: MACRO
LDD \1
ADD \2
STD \1
ENDM
