SBK is a Super FX instruction that uses Bulk Processing. It stores the value in the source register to the address in the ram address cache.

The source register should be specified in advance using WITH or FROM. Otherwise, R0 serves as the default.

Syntax

SBK

Example

Let:

(70:3230h) = 51h
(70:3231h) = 49h
RAMBR = 70h

After executing this program:

LM   R1, (3230h)
INC  R1
SBK

We have:

R1 = 4952h
(70:3230h) = 52h
(70:3231h) = 49h
