  * @brief     AT32F4xx 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
  *                - Configure the clock system and the external SRAM to
  *                  be used as data memory (optional, to be enabled by user)
  *                - 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.
