| 5 | * @brief STM32F105xC Devices vector table for Atollic toolchain. |
||
| 6 | * This module performs: |
||
| 7 | * - Set the initial SP |
||
| 8 | * - Set the initial PC == Reset_Handler, |
||
| 9 | * - Set the vector table entries with the exceptions ISR address |
||
| 10 | * - Configure the clock system |
||
| 11 | * - Branches to main in the C library (which eventually |
||
| 12 | * calls main()). |
||
| 13 | * After Reset the Cortex-M3 processor is in Thread mode, |
||
| 14 | * priority is Privileged, and the Stack is set to Main. |
