2;* File Name : startup_stm32c011xx.s
3;* Author : MCD Application Team
4;* Description : STM32C011xx devices vector table for EWARM toolchain.
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;* - Branches to main in the C library (which eventually
11;* calls main()).
12;* After Reset the Cortex-M0+ processor is in Thread mode,
13;* priority is Privileged, and the Stack is set to Main.

26; The modules in this file are included in the libraries, and may be replaced
27; by any user-defined modules that define the PUBLIC symbol _program_start or
28; a user defined start symbol.
29; To override the cstartup defined in the library, simply add your modified
30; version to the workbench project.
31;
32; The vector table is normally located at address 0.
33; When debugging in RAM, it can be located in RAM, aligned to at least 2^6.
34; The name "__vector_table" has special meaning for C-SPY:
35; it is where the SP start value is found, and the NVIC vector
36; table register (VTOR) is initialized to this address if != 0.
