+  *            This module performs:

+  *                - 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

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