Unaligned Store Word (ustw)

Syntax

ustw $s_reg, address

Description

Unaligned Store Word stores the two least significant bytes of the source register in the memory location specified by the effective address. The address does not have to be aligned on a 2-byte boundary, it can be any byte address.

Note   The assembler destroys the contents of temporary registers $at, $t9, $t10, $t11, and $t12 for this instruction.
