File      : stm32c011xx_Vectors.s
Purpose   : Exception and interrupt vectors for stm32c011xx devices.

Additional information:
  Preprocessor Definitions
    __NO_EXTERNAL_INTERRUPTS
      If defined,
        the vector table will contain only the internal exceptions
        and interrupts.
    __VECTORS_IN_RAM
      If defined,
        an area of RAM, large enough to store the vector table,
        will be reserved.

    __OPTIMIZATION_SMALL
      If defined,
        all weak definitions of interrupt handlers will share the
        same implementation.
      If not defined,
        all weak definitions of interrupt handlers will be defined
        with their own implementation.
