AMF specifies the ALU or MAC operation, in this case:
AMF = 10010 for xop + yop + C
AMF = 10011 for xop + yop
(Note that xop + C is a special case of xop + yop + C with yop=0.)
Z:
Xop:
(xop + constant) Conditional ALU/MAC operation, Instruction Type 9:

AMF specifies the ALU or MAC operation, in this case:
AMF = 10010 for xop + constant + C
AMF = 10011 for xop + constant
Z:
Xop:
BO, CC, and YY specify the constant (see Appendix A, Instruction Coding).
