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