Is the MMIO derive limited to certain types?

[jamesmunns]

Do you limit all the fields to be specific (integer?) types?

I know someone mentioned that using a field as bool and reading a value other than 0/1 would be UB, and using volatile ops on values larger than the atomic load width would probably be suspicious as well.

I'm also interested if/how you handle arrays!

It would probably be good to document what fields the derive does/doesn't work with.

There are currently no restrictions on the types you can use, other than the ability to pass pointers to them to read_volatile and write_volatile. I'm using it with a bitbybit::bitfield, for example.

I agree docs would be useful, or an expanded example.
