| * @brief STM32WB55xx devices vector table GCC toolchain. |
| * 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. |
