对内存映射硬件寄存器的易失性访问

用法

use volatile_register::RW;

// Create a struct that represents the memory mapped register block
/// Nested Vector Interrupt Controller
#[repr(C)]
pub struct Nvic {
    /// Interrupt Set-Enable
    pub iser: [RW<u32>; 8],
    reserved0: [u32; 24],
    /// Interrupt Clear-Enable
    pub icer: [RW<u32>; 8],
    reserved1: [u32; 24],
    // .. more registers ..
}

// Access the registers by casting the base address of the register block
// to the previously declared `struct`
let nvic = 0xE000_E100 as *const Nvic;
// Unsafe because the compiler can't verify the address is correct
unsafe { (*nvic).iser[0].write(1) }
