rp235x-hal 0.4.0

//! Universal Asynchronous Receiver Transmitter (UART)
//!
//! See [Section 12.1](https://rptl.io/rp2350-datasheet#section_uart) of the datasheet for more details.
//!
//! ## Usage
//!
//! See [examples/uart.rs](https://github.com/rp-rs/rp-hal/tree/main/rp235x-hal-examples/src/bin/uart.rs) for a more complete example.
//!
//! ```no_run
