bogdanm 0:9b334a45a8ff 7 * @brief STM32F030x8 devices vector table for Atollic TrueSTUDIO toolchain.
bogdanm 0:9b334a45a8ff 8 * This module performs:
bogdanm 0:9b334a45a8ff 9 * - Set the initial SP
bogdanm 0:9b334a45a8ff 10 * - Set the initial PC == Reset_Handler,
bogdanm 0:9b334a45a8ff 11 * - Set the vector table entries with the exceptions ISR address
bogdanm 0:9b334a45a8ff 12 * - Branches to main in the C library (which eventually
bogdanm 0:9b334a45a8ff 13 * calls main()).
bogdanm 0:9b334a45a8ff 14 * After Reset the Cortex-M0 processor is in Thread mode,
bogdanm 0:9b334a45a8ff 15 * priority is Privileged, and the Stack is set to Main.
