   6 ;* Description        : STM32F072x8/STM32F072xB devices vector table for MDK-ARM_MICRO toolchain.
   7 ;*                      This module performs:
   8 ;*                      - Set the initial SP
   9 ;*                      - Set the initial PC == Reset_Handler
  10 ;*                      - Set the vector table entries with the exceptions ISR address
  11 ;*                      - Branches to __main in the C library (which eventually
  12 ;*                        calls main()).
  13 ;*                      After Reset the CortexM0 processor is in Thread mode,
  14 ;*                      priority is Privileged, and the Stack is set to Main.
