FUNCTION
DESCRIPTION
rsrc2 into rdest. The byte from rsrc1 is packed into the second-least-significant byte of rdest; the byte from rsrc2 is
packed into the least-significant byte of rdest. The two most-significant bytes of rdest are filled with zeros.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
