26.1.1 Operand identifiers and specification methods
the instruction operand identifier (refer to the assembler specifications for details). When there are two or more
methods, select one of them. Upper case letters and the symbols #, !, $ and [ ] are keywords and must be written as
they are. Each symbol has the following meaning.
