skipped.
* **CTR-test=0, CTi=1**: CTR decrements on a per-element basis
if `BO[2]` is zero and a masked-out element is skipped
- (`sz=0` and predicate bit is zero). This one case is the
+ (`sz=0` and predicate bit is zero). This one special case is the
**opposite** of other combinations.
* **CTR-test=1, CTi=0**: CTR decrements on a per-element basis
if `BO[2]` is zero and the Condition Test succeeds.
