|
* @brief STM32WLE5xx devices vector table for 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-M4 processor is in Thread mode, |
|
* priority is Privileged, and the Stack is set to Main. |
