-  * @brief     STM32L476xx devices vector table GCC toolchain.
-  *            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.
