  5.   * @brief     STM32WB35xx devices vector table GCC 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.   *                - Branches to main in the C library (which eventually

  11.   *                  calls main()).

  12.   *            After Reset the Cortex-M4 processor is in Thread mode,

  13.   *            priority is Privileged, and the Stack is set to Main.
