|

* 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
|
||||
* - Configure 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 Cortex-M3 processor is in Thread mode,
|
||||
* priority is Privileged, and the Stack is set to Main.
