+@cindex MSP 430 macros
+The macro syntax used on the MSP 430 is like that described in the MSP
+430 Family Assembler Specification.  Normal @code{@value{AS}}
+macros should still work.
+
+Additional built-in macros are:
+
+@table @code
+
+@item llo(exp) 
+Extracts least significant word from 32-bit expression 'exp'.
+
+@item lhi(exp)
+Extracts most significant word from 32-bit expression 'exp'.
+
+@item hlo(exp)
+Extracts 3rd word from 64-bit expression 'exp'.
+
+@item 	hhi(exp) 
+Extracts 4rd word from 64-bit expression 'exp'.
+
+@end table
+
+They normally being used as an immediate source operand.

+@cindex MSP 430 line comment character
+@samp{;} is the line comment character.

+@cindex MSP 430 identifiers
+The character @samp{$} in jump instructions indicates current location and

+@node MSP430-Regs
+@subsection Register Names
+
+@cindex MSP 430 register names
+@cindex register names, MSP 430
+General-purpose registers are represented by predefined symbols of the
+form @samp{r@var{N}} (for global registers), where @var{N} represents
+a number between @code{0} and @code{15}.  The leading
+letters may be in either upper or lower case; for example, @samp{r13}
+and @samp{R7} are both valid register names.
+
+@cindex special purpose registers, MSP 430
+Register names @samp{PC}, @samp{SP} and @samp{SR} cannot be used as register names
+and will be treated as variables. Use @samp{r0}, @samp{r1}, and @samp{r2} instead.
