Macro Assembler
4.3.2 Characters
The character set used is standard 7 bit ASCII. Alphabetic case is significant for identifiers, but not
mnemonics and reserved words. Tabs are treated as equivalent to spaces.
4.3.2.1 Delimiters
All numbers and identifiers must be delimited by white space, non-alphanumeric characters or the
end of a line.
4.3.2.2 Special Characters
There are a few characters that are special in certain contexts. Within a macro body, the character & is
used for token concatenation. To use the bitwise & operator within a macro body, escape it by using
&& instead. In a macro argument list, the angle brackets < and > are used to quote macro arguments.
4.3.3 Comments
An assembly comment is initiated with a semicolon that is not part of a string or character constant.
contain C or C++ style comments using the standard /* ... */ and // syntax.
4.3.3.1 Special Comment Strings
Several comment strings are appended to assembler instructions by the code generator. These are
typically used by the assembler optimizer.
the commented instruction is associated with a variable that was declared as volatile in the C
source code. Accesses to this location which appear to be redundant will not be removed by the
assembler optimizer if this string is present.

If the assembly file is first processed by the C preprocessor, see Section 2.4.11, then it may also
The comment string ;volatile is used to indicate that the memory location being accessed in
