TO is a Super FX register prefix instruction that specifies the destination register. Any register from R0 to R15 can be specified. The exception is when the B Flag is set (i.e. a WITH instruction is executed immediately before) in which case a MOVE is executed instead with WITH acting as the source and TO as the destination.
No flags are affected.
