* @version V1.0
* @date 12/23/2009
* @brief STM32F10x Medium Density Devices Startup code.
* This module performs:
* - Set the initial SP
* - Set the vector table entries with the exceptions ISR address
* - Initialize data and bss
* - Setup the microcontroller system.
* - Call the application's entry point.
* After Reset the Cortex-M3 processor is in Thread mode,
* priority is Privileged, and the Stack is set to Main.
