;* Description        : STM32F042 Devices Devices vector table for 
;*                      EWARM toolchain.
;*                      This module performs:
;*                      - Set the initial SP
;*                      - Set the initial PC == iar_program_start,
;*                      - Set the vector table entries with the exceptions ISR 
;*                        address.
;*                      After Reset the Cortex-M0 processor is in Thread mode,
;*                      priority is Privileged, and the Stack is set to Main.

;
; 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.
