- ;* Description : STM32F071x8/STM32F071xB 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 CortexM0 processor is in Thread mode,
- ;* priority is Privileged, and the Stack is set to Main.
