//! Provides a single point of access to the hardware devices associated with
//! the AVR CPU on which we are running.
//!
//! This struct is your first port of call for accessing a pin, timer, or
//! any other hardware component which we have support for.
//!
//! It is implemented as a global singleton, a reference is obtained using
//! the provided instance() function.  From here, you can then obtain
//! references to all the supported low-level hardware devices.
//!
//! # Example usage
//! ```rust
//! use avr_oxide::hal::atmega4809;
//!
//! fn use_hardware() {
//!   let hardware = atmega328p::hardware::instance();
//!
//!   // Get a reference to Port D
//!   let portd = &hardware.portd;
//! }
//! ```
