mbed_official 114:fe4fe5cfc3a3 5 * @brief STM32L031xx Devices vector table for Atollic TrueSTUDIO toolchain.
mbed_official 114:fe4fe5cfc3a3 6 * This module performs:
mbed_official 114:fe4fe5cfc3a3 7 * - Set the initial SP
mbed_official 114:fe4fe5cfc3a3 8 * - Set the initial PC == Reset_Handler,
mbed_official 114:fe4fe5cfc3a3 9 * - Set the vector table entries with the exceptions ISR address
mbed_official 114:fe4fe5cfc3a3 10 * - Branches to main in the C library (which eventually
mbed_official 114:fe4fe5cfc3a3 11 * calls main()).
mbed_official 114:fe4fe5cfc3a3 12 * After Reset the Cortex-M0+ processor is in Thread mode,
mbed_official 114:fe4fe5cfc3a3 13 * priority is Privileged, and the Stack is set to Main.
