Description
The content of the rs register (word data) is transferred to the specified memory location. The rb
register contains the memory address to be accessed. Following data transfer, the address in the
rb
register is incremented by 4.
Caution
The rb register and the displacement must specify a word boundary address (two least significant
bits = 0). Specifying an odd address causes an address misaligned exception.
