## Predicate MASK Encoding
-One bit indicates the mode: CR or Int predication. The two types may not be mixed.
+One bit (`MASKMODE`) indicates the mode: CR or Int predication. The two types may not be mixed.
Integer Twin predication has a second set if 3 bits that uses the same encoding thus allowing either the same register (r3 or r10) to be used for both src and dest, or different regs (one for src, one for dest).
