 Operand expression type qualifier is an optional field in the instruction operand, to determines the type of the expression field of an operand. The @code{@@} is required. CR16 architecture uses one of the following expression qualifiers:

+@cindex CR16 line comment character
+The presence of a @samp{#} on a line indicates the start of a comment
+that extends to the end of the current line.  If the @samp{#} appears
+as the first character of a line, the whole line is treated as a
+comment, but in this case the line can also be a logical line number
+directive (@pxref{Comments}) or a preprocessor control command
+(@pxref{Preprocessing}).
