10. APPENDIX B ( Instruction Grouping in MB8686X )
Group B is divided into Group B#0 and Group B#1. Group B#0 instructions affect condition codes, while Group B#1
does not. FPU instructions are not supported, and there is therefore no Group C.

Simultaneously executable instruction combinations
Through the addition of a 2nd ALU to the MB8686X, it has become possible to execute 2 ALU instructions at the same
time. The 2nd ALU can only execute instructions which do not affect condition codes.
