  6. ;* Description : STM32F30x devices vector table for MDK-ARM toolchain.
  7. ;* This module performs:
  8. ;* - Set the initial SP
  9. ;* - Set the initial PC == Reset_Handler
  10. ;* - Set the vector table entries with the exceptions ISR address
  11. ;* - Branches to __main in the C library (which eventually
  12. ;* calls main()).
  13. ;* After Reset the CortexM4 processor is in Thread mode,
  14. ;* priority is Privileged, and the Stack is set to Main.
