## Finding corresponding sections in the PAC
* `dk_pac/src/lib.rs` defines the single peripherals with their register block addresses and contains a struct definition for the `struct Peripherals`. There are two methods for this struct: `take()` and `steal()`. `take()` assures, that only one instance of this can exist. Hence, it's safe. Note that `take()` is only available with the `critical-section` feature enabled.
* `dk_pac/src/lib.rs` defines the singleton peripherals as part of a larger `struct Peripherals`. There are two methods for this struct: `take()` and `steal()`. `take()` assures, that only one instance of this can exist. Hence, it's safe. Note that `take()` is only available with the `critical-section` feature enabled.
* `dk_pac/src/uarte0.rs` defines a struct that contains all the registers of the `UARTE0` register block. The `enable` field represents the register of the same name.
