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)

Extracts least significant word from 32-bit expression exp.

lhi(exp)

Extracts most significant word from 32-bit expression exp.

hlo(exp)

Extracts 3rd word from 64-bit expression exp.

hhi(exp)

Extracts 4th word from 64-bit expression exp.

They normally being used as an immediate source operand.

    mov       #llo(1), r10    ;       == mov  #1, r10
    mov #lhi(1), r10    ;       == mov  #0, r10
