I imagine that there are AVR devices which have IO ports where only half of the bits are actually connected to pins.

We might want to look into something like defining PB1, PB2, ... registers for each generated module. That way, if you're using the library and you try to use a pin that doesn't exist, it will hit a hard error.

My favorite example of this is the attiny85 8 pin device: https://docs.rs/avrd/0.1.1/avrd/attiny85/index.html
attiny 4/5/9/10 six pin devices are other examples: https://docs.rs/avrd/0.1.1/avrd/attiny10/index.html
