7 * @brief STM32F103xB Devices vector table for Atollic toolchain.
8 * This module performs:
10 * - Set the initial PC == Reset_Handler,
11 * - Set the vector table entries with the exceptions ISR address
12 * - Configure the clock system
13 * - Branches to main in the C library (which eventually
15 * After Reset the Cortex-M3 processor is in Thread mode,
16 * priority is Privileged, and the Stack is set to Main.
