Notes 1.
The operands of ADDC, SUB, SUBC, AND, OR, XOR, and CMP are the same as that of ADD.
2.
Either the second operand is not used, or the second operand is not an operand address.
3.
The operands of ROL, RORC, ROLC, SHR, and SHL are the same as that of ROR.
4.
The operands of XCHM, CMPME, CMPMNE, CMPMNC, and CMPMC are the same as that of MOVM.
5.
The operands of XCHBK, CMPBKE, CMPBKNE, CMPBKNC, and CMPBKC are the same as that of
MOVBK.
6.
The code length of some instructions having saddr2 as saddr in this combination is short.
