FUNCTION
DESCRIPTION
rsrc2 into rdest. The halfword from rsrc1 is packed into the most-significant halfword of rdest; the halfword from rsrc2
is packed into the least-significant halfword of rdest.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is unchanged.
EXAMPLES
r30 = 0x12345678, r40 = 0xaabbccdd
r10 = 0, r40 = 0xaabbccdd, r30 = 0x12345678
r20 = 1, r40 = 0xaabbccdd, r30 = 0x12345678
