* @brief STM32F10x Low Density Devices vector table for Atollic toolchain. |
| 8 |
* This module performs: |
| 9 |
* - Set the initial SP |
| 10 |
* - Set the initial PC == Reset_Handler, |
| 11 |
* - Set the vector table entries with the exceptions ISR address. |
| 12 |
* - Configure the clock system |
| 13 |
* - Branches to main in the C library (which eventually |
| 14 |
* calls main()). |
| 15 |
* After Reset the Cortex-M3 processor is in Thread mode, |
| 16 |
* priority is Privileged, and the Stack is set to Main. |
