- * @brief STM32L475xx devices vector table for GCC toolchain.\r
- * This module performs:\r
- * - Set the initial SP\r
- * - Set the initial PC == Reset_Handler,\r
- * - Set the vector table entries with the exceptions ISR address,\r
- * - Configure the clock system \r
- * - Branches to main in the C library (which eventually\r
- * calls main()).\r
- * After Reset the Cortex-M4 processor is in Thread mode,\r
- * priority is Privileged, and the Stack is set to Main.\r
