modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r30 = 3, r40 = 4
r10 = 0, r60 = 0x1000, r30 = 3
r20 = 1, r50 = 0x1000, r60 = 0x1000
r70 = 0x80000000, r40 = 4
r70 = 0x80000000

Initial Values
operation sets the destination register, rdest, to 1 if the two arguments, rsrc1 and rsrc2, are not equal;
operation optionally takes a guard, specified in rguard. If a guard is present, its LSB controls the
