Section 6 Instruction Descriptions
6.4.63
Format
SWAP.B
SWAP.W
Description
Swaps the upper and lower bytes of the general register Rm data, and stores the result in Rn. If a
byte is specified, bits 0 to 7 of Rm are swapped for bits 8 to 15. The upper 16 bits of Rm are
transferred to the upper 16 bits of Rn. If a word is specified, bits 0 to 15 of Rm are swapped for
bits 16 to 31.
