| ;* Description : STM32L010xB Ultra Low Power Devices vector |
| ;* This module performs: |
| ;* - Set the initial SP |
| ;* - Set the initial PC == _iar_program_start, |
| ;* - 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-M0+ processor is in Thread mode, |
| ;* priority is Privileged, and the Stack is set to Main. |

| ; The modules in this file are included in the libraries, and may be replaced |
| ; by any user-defined modules that define the PUBLIC symbol _program_start or |
| ; a user defined start symbol. |
| ; To override the cstartup defined in the library, simply add your modified |
| ; version to the workbench project. |
| ; |
| ; The vector table is normally located at address 0. |
| ; When debugging in RAM, it can be located in RAM, aligned to at least 2^6. |
| ; The name "__vector_table" has special meaning for C-SPY: |
| ; it is where the SP start value is found, and the NVIC vector |
| ; table register (VTOR) is initialized to this address if != 0. |
