- * @version V1.1.0
- * @date 12-Sept-2014
- * @brief STM32F334x4/STM32F334x6/STM32F334x8 devices vector table for
- * Atollic TrueSTUDIO 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
- * - 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.
