//! Low level access to Cortex-M processors
//!
//! This crate provides:
//!
//! - Access to core peripherals like NVIC, SCB and SysTick.
//! - Access to core registers like CONTROL, MSP and PSR.
//! - Interrupt manipulation mechanisms
//! - Data structures like the vector table
//! - Safe wrappers around assembly instructions like `bkpt`
