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.

Syntax

Example

Let:

R6 = 7106h
R3 = 0028h

After executing this program:

FROM R6
TO   R4
ADD  R3

We have:

R4 = 712eh
