| 4 | ;* Description : STM32F030x8 devices vector table for MDK-ARM toolchain. | |
| 5 | ;* This module performs: | |
| 6 | ;* - Set the initial SP | |
| 7 | ;* - Set the initial PC == Reset_Handler | |
| 8 | ;* - Set the vector table entries with the exceptions ISR address | |
| 9 | ;* - Branches to __main in the C library (which eventually | |
| 10 | ;* calls main()). | |
| 11 | ;* After Reset the CortexM0 processor is in Thread mode, | |
| 12 | ;* priority is Privileged, and the Stack is set to Main. | |
