* Kinda. The syntax is like:

```
register Foo {
    my_field: int = 0..12,
    other_field: bool = 15,
}
```

The integer here has endianness, the data that represents the register has endianness. You can also specify the reset value of a register and guess what, that too has endianness.
The inner data then also has LSB0 or MSB0.

It's maddening
