-Operations that actually produce or alter CR Field as a result do not
-also in turn have an Rc=1 mode. However it makes no sense to try to test
-the 4 bits of a CR Field for being equal or not equal to zero. Moreover,
-the result is already in the form that is desired: it is a CR field.

There are two primary different types of CR operations:
