| 4 | ;* Description : STM32C011xx devices vector table for EWARM toolchain. |
---|
| 5 | ;* This module performs: |
---|
| 6 | ;* - Set the initial SP |
---|
| 7 | ;* - Set the initial PC == __iar_program_start, |
---|
| 8 | ;* - Set the vector table entries with the exceptions ISR |
---|
| 9 | ;* address |
---|
| 10 | ;* - Branches to main in the C library (which eventually |
---|
| 11 | ;* calls main()). |
---|
| 12 | ;* After Reset the Cortex-M0+ processor is in Thread mode, |
---|
| 13 | ;* priority is Privileged, and the Stack is set to Main. |
