;* Description        : STM32F10x XL-Density Devices vector table for MDK-ARM 
;*                      toolchain. 
;*                      This module performs:
;*                      - Set the initial SP
;*                      - Set the initial PC == Reset_Handler
;*                      - Set the vector table entries with the exceptions ISR address
;*                      - Configure the clock system and also configure the external 
;*                        SRAM mounted on STM3210E-EVAL board to be used as data 
;*                        memory (optional, to be enabled by user)
;*                      - 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.
