   7   * @brief     STM32F334x4/STM32F334x6/STM32F334x8 devices vector table for
   8   *            Atollic TrueSTUDIO toolchain.
   9   *            This module performs:
  10   *                - Set the initial SP
  11   *                - Set the initial PC == Reset_Handler,
  12   *                - Set the vector table entries with the exceptions ISR address,
  13   *                - Configure the clock system
  14   *                - Branches to main in the C library (which eventually
  15   *                  calls main()).
  16   *            After Reset the Cortex-M4 processor is in Thread mode,
  17   *            priority is Privileged, and the Stack is set to Main.
