* Heyyy, I got it! 😎
``cannot borrow `*phy` as mutable more than once at a time``
I was doing this:

```impl
type RxToken<'a> = RT1062PhyRxToken<> where Self: 'a;   
type TxToken<'a> = RT1062PhyTxToken<> where Self: 'a;
```

and I needed:

`type RxToken<'a> = RT1062PhyRxToken<'a> where Self: 'a; type TxToken<'a> = RT1062PhyTxToken<'a> where Self: 'a;`
