* @brief STM32F10x Medium Density Devices vector table for RIDE7 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. |
