| * @brief CMSIS STM32G4xx Device Peripheral Access Layer Header File. |
| * |
| * The file is the unique include file that the application programmer |
| * is using in the C source code, usually in main.c. This file contains: |
| * - Configuration section that allows to select: |
| * - The STM32G4xx device used in the target application |
| * - To use or not the peripheralÂ’s drivers in application code(i.e. |
| * code will be based on direct access to peripheralÂ’s registers |
| * rather than drivers API), this option is controlled by |
| * "#define USE_HAL_DRIVER" |
| * |
