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.
Operation:
