yes, you can see that from the documentation on PriorityEncoder,
whiiich.... you can reaaaad... in the actual source code docstring...
so it's inverted:
" If any bit in ``i`` is asserted, ``n`` is low and ``o`` indicates
the least significant
asserted bit. Otherwise, ``n`` is high and ``o`` is ``0``.
n : Signal, out
Invalid: no input bits are asserted.
