Detailed Description

Hardware Abstraction Layer (HAL) common type definitions.

This header file defines basic macros and types used throughout the HAL and low-level drivers:

• __IO : Volatile qualifier for memory-mapped I/O registers.
• NULL : Null pointer definition for pointer initialization and checks.

These definitions help standardize low-level coding practices across different architectures and modules.
