* 1. SUBW and CMPW are the same as ADDW.
2nd Operand
MOVM, XCHW, ADDW, SUBW, CMPW, MULUW, MULW, DIVUX, INCW, DECW, SHRW, SHLW, PUSH, POP,
ADDWG, SUBWG, PUSHU, POPU, MOVTBLW, MACW, MACSW, SACW
2. There is no 2nd operand, or the 2nd operand is not an operand address.
3. If saddrp is saddrp2 in this combination, there is a short code length instruction.
4. MULUW and DIVUX are the same as MULW.
