7.7.8 Instructions where format is changed (Excluding AnUSCPU dedicated
instructions)
Instructions using the accumulator for the AnSCPU are changed in their format, since the QnUCPU/
QnASCPU do not have the accumulator (A0, A1).
The accumulator A0 is converted to SD718, the accumulator A1 is converted to SD719.
