   7   * @brief     STM32F30x Devices vector table for RIDE7 toolchain.
   8   *            This module performs:
   9   *                - Set the initial SP
  10   *                - Set the initial PC == Reset_Handler,
  11   *                - Set the vector table entries with the exceptions ISR address
  12   *                - Configure the clock system and the external SRAM mounted on
  13   *                  STM3230C-EVAL board to be used as data memory (optional,
  14   *                  to be enabled by user)
  15   *                - Branches to main in the C library (which eventually
  16   *                  calls main()).
  17   *            After Reset the Cortex-M4 processor is in Thread mode,
  18   *            priority is Privileged, and the Stack is set to Main.
