The following code snippet does the trick, leaving the results in general registers 0 and 1.
LLC 0,BYTE RISBGZ 1,0,62,63,-4 SRL 0,6 AHI 0,C'1' (or CA'1' for results in ASCII) AHI 1,C'1' (or CA'1' for results in ASCII) (I consider ROTATE THEN INSERT SELECTED BITS to be the sexiest instruction in the architecture.)
