;* File Name : stm32f10x_startup.s
;* Author : MCD Application Team
;* Date First Issued : 02/05/2007
;* 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.
