* 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 Cortex-M0 processor is in Thread mode,
|

* priority is Privileged, and the Stack is set to Main.
