PORTA isn't a full byte, but using PORTB instead, it still won't have
the desired effect. What it does is leave the port alone in one
condition and toggle it in the other, rather than having one pin always
follow and the other be the inverse.

Thanks for the suggestion, though, it's one I hadn't tried!

Cheerful regards,
