6/// Defines the layout and access rules to a memory-mapped register.
7///
8/// This macros does not define the memory-mapped register itself.
9/// It generates type definitions for its layout and access rules.
10/// Use the [`reg`] macro to define memory-mapped registers based on type definitions.
11///
12/// # Examples
13/// ```
14/// use regs_macros::*;
15///
16/// regspec!(CR as u32, bits {
17///     EN[31],
18///     RYD[24, ro],
19///     STAT[16;2],
20/// });
21/// ```
