+ * - Set the initial PC == Reset_Handler,\r
+ * - Set the vector table entries with the exceptions ISR address\r
+ * - Branches to main in the C library (which eventually\r
+ * calls main()).\r
+ * After Reset the Cortex-M3 processor is in Thread mode,\r
+ * priority is Privileged, and the Stack is set to Main.\r
