I have this bit:
```rust
                                match $apb {
                                    ApbNum::One => {
                                        rcc.apb1enr1.modify(|_, w| w.[<$tim en>]().set_bit());
                                        rcc.apb1rstr1.modify(|_, w| w.[<$tim rst>]().set_bit());
                                        rcc.apb1rstr1.modify(|_, w| w.[<$tim rst>]().clear_bit());
                                    }
                                    _ => {
                                        rcc.apb2enr.modify(|_, w| w.[<$tim en>]().set_bit());
                                        rcc.apb2rstr.modify(|_, w| w.[<$tim rst>]().set_bit());
                                        rcc.apb2rstr.modify(|_, w| w.[<$tim rst>]().clear_bit());
                                    }
                                }
``` (etc), and it's somehow calling the wrong branch?
