+  * @brief     STM32L073xx Devices vector table for 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
+  *                - Branches to main in the C library (which eventually
+  *                  calls main()).
+  *            After Reset the Cortex-M0+ processor is in Thread mode,
+  *            priority is Privileged, and the Stack is set to Main.
