The macro syntax used on the MSP 430 is like that described in the MSP
430 Family Assembler Specification.  Normal as
macros should still work.
   
Additional built-in macros are:
llo(exp)lhi(exp)hlo(exp)hhi(exp)They normally being used as an immediate source operand.
         mov	#llo(1), r10	;	== mov	#1, r10
         mov	#lhi(1), r10	;	== mov	#0, r10
