;* Description        : 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 CortexM3 processor is in Thread mode,
;*                      priority is Privileged, and the Stack is set to Main.
