mbed_official 630:825f75ca301e 7 * @brief STM32F031x4/STM32F031x6 devices vector table for Atollic TrueSTUDIO toolchain.
mbed_official 630:825f75ca301e 8 * This module performs:
mbed_official 630:825f75ca301e 9 * - Set the initial SP
mbed_official 630:825f75ca301e 10 * - Set the initial PC == Reset_Handler,
mbed_official 630:825f75ca301e 11 * - Set the vector table entries with the exceptions ISR address
mbed_official 630:825f75ca301e 12 * - Branches to main in the C library (which eventually
mbed_official 630:825f75ca301e 13 * calls main()).
mbed_official 630:825f75ca301e 14 * After Reset the Cortex-M0 processor is in Thread mode,
mbed_official 630:825f75ca301e 15 * priority is Privileged, and the Stack is set to Main.
