Parallel Issue
This instruction can be issued in parallel with specific other 16-bit
instructions. For details, see
Example
r3 = byteop2p (r1:0, r3:2) (rndl) ;
r3 = byteop2p (r1:0, r3:2) (rndh) ;
r3 = byteop2p (r1:0, r3:2) (tl) ;
r3 = byteop2p (r1:0, r3:2) (th) ;
r3 = byteop2p (r1:0, r3:2) (rndl, r) ;
r3 = byteop2p (r1:0, r3:2) (rndh, r) ;
r3 = byteop2p (r1:0, r3:2) (tl, r) ;
r3 = byteop2p (r1:0, r3:2) (th, r) ;
