- ;* Description : STM32L152XD-X Devices vector 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.
- ;* - Configure the system clock
- ;* - Branches to __main in the C library (which eventually
- ;* calls main()).
- ;* After Reset the Cortex-M3 processor is in Thread mode,
- ;* priority is Privileged, and the Stack is set to Main.
