| ;* Description : STM32l062xx Devices vector table for MDK-ARM toolchain. |
| ;* This module performs: |
| ;* - Set the initial SP |
| ;* - Set the initial PC == Reset_Handler |
| ;* - Set the vector table entries with the exceptions ISR address |
| ;* - Branches to __main in the C library (which eventually |
| ;* calls main()). |
| ;* After Reset the Cortex-M0+ processor is in Thread mode, |
| ;* priority is Privileged, and the Stack is set to Main. |
