| * @brief STM32L476xx devices vector table GCC 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. | |
