;* Description        : STM32F042x4/STM32F042x6 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.
