C.1.5.1.2.3 Data ALU Results/Move Compatibility Summary
Figure C-16 summarizes what happens when Data ALU operation results of a certain range are stored in
the destination register, and the register is read by a certain kind of move.
All cases where "move out type"=SP and "move out result"=WRONG can be corrected by rounding in the
instruction (using the .S option). The case where "move out type"=SP and "move out result"=TRUNC can
also be corrected by using the .S option.
