  4. ;* Description        : STM32L072xx Ultra Low Power Devices vector

  5. ;*                      This module performs:

  6. ;*                      - Set the initial SP

  7. ;*                      - Set the initial PC == _iar_program_start,

  8. ;*                      - Set the vector table entries with the exceptions ISR

  9. ;*                        address.

  10. ;*                      - Configure the system clock

  11. ;*                      - Branches to main in the C library (which eventually

  12. ;*                        calls main()).

  13. ;*                      After Reset the Cortex-M0+ processor is in Thread mode,

  14. ;*                      priority is Privileged, and the Stack is set to Main.

  42. ; The modules in this file are included in the libraries, and may be replaced

  43. ; by any user-defined modules that define the PUBLIC symbol _program_start or

  45. ; To override the cstartup defined in the library, simply add your modified

  46. ; version to the workbench project.

  48. ; The vector table is normally located at address 0.

  49. ; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.

  50. ; The name "__vector_table" has special meaning for C-SPY:

  51. ; it is where the SP start value is found, and the NVIC vector

  52. ; table register (VTOR) is initialized to this address if != 0.
