   5   * @brief     STM32F427xx Devices vector table for GCC based toolchains.
   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.
