SMS (Store to raM Short address) is a Super FX instruction that stores a value to the Game Pak. The bank must be specified with RAMB.

The selectable RAM address must be an even number between 0 and 510.

The number of cycles varies because of the RAM buffer.

The ALT0 state is restored.

Syntax

SMS (yy), Rn

Example

Let:

R11 = abcdh
RAMBR = 71h

After executing this program:

 Syntax              Opcode
 SMS (194h), R11     3e ab ca

We have:

(71:0194h) = cdh
(71:0195h) = abh
