//! `attiny-hal`
//! =============
//! Common HAL (hardware abstraction layer) for ATtiny* microcontrollers.
//!
//! **Note**: This version of the documentation was built for
#![cfg_attr(feature = "attiny85", doc = "**ATtiny85**.")]
#![cfg_attr(feature = "attiny88", doc = "**ATtiny88**.")]
#![cfg_attr(feature = "attiny167", doc = "**ATtiny167**.")]
#![cfg_attr(feature = "attiny2313", doc = "**ATtiny2313**.")]
//! This means that only items which are available for this MCU are visible.  If you are using
//! a different chip, try building the documentation locally with:
//!
//! ```text
//! cargo doc --features <your-mcu> --open
//! ```
