SYNTAX
FUNCTION
DESCRIPTION
8-bit bytes of rsrc1 and rsrc2. The bytes in rsrc1 are considered unsigned values; the bytes in rsrc2 are considered
signed. The four sums are clipped into the unsigned range [255..0] (or [0xff..0]); thus, the final byte sums are
unsigned. All computations are performed without loss of precision.
controls the modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not
changed.
