DESCRIPTION
rsrc1 and rsrc2 into rdest. The second-most-significant byte from rsrc2 is packed into the least-significant byte of
rdest; the second-most-significant byte from rsrc1 is packed into the second-least-significant byte of rdest; the most-
significant byte from rsrc2 is packed into the second-most-significant byte of rdest; and the most-significant byte from
rsrc1 is packed into the most-significant byte of rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
