I’m pretty sure that the IOPORT stuff is part of the m0+ spec ( one of the differences between the m0 and m0+, iirc)
Other m0+ processors like the samd also have IOPORT.
(Fast pin manipulation being a “required feature” for replacing 8bit chips.)
(Not so sure about putting “other stuff” on the fast, direct, bus.)
