//! # System Control
//!
//! ## Overview
//!
//! This `system` module defines the available radio peripherals and provides an
//! interface to control and configure radio clocks.

///
/// This enum represents various hardware peripherals that can be enabled
/// by the system's clock control. Depending on the target device, different
/// peripherals will be available for enabling.
// FIXME: This enum needs to be public because it's exposed via a bunch of traits, but it's not
// useful to users.
