+  *
+  *          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 peripheral’s drivers in application code(i.e.
+  *                code will be based on direct access to peripheral’s registers
+  *                rather than drivers API), this option is controlled by
+  *                "#define USE_HAL_DRIVER"

+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;* Description        : STM32G441xx Mainstream devices vector table for
+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+;*                      MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.

+  *            After Reset the Cortex-M4 processor is in Thread mode,

+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address,
+  *                - Configure the clock system
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M4 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.

+  *            This module performs:
+  *                - Set the initial SP
+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address,
+  *                - Configure the clock system
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M4 processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.

+  *                - Set the initial PC == Reset_Handler,
+  *                - Set the vector table entries with the exceptions ISR address,

+  *                - Branches to main in the C library (which eventually

+  *            After Reset the Cortex-M4 processor is in Thread mode,
