DESCRIPTION
arguments rsrc1 and rsrc2 are considered unsigned integers.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 0x80, r40 = 0x7f
r10 = 0, r60 = 0x12345678,
r70 = 0xabc
r20 = 1, r60 = 0x12345678,
r70 = 0xabc
