+;* Description        : STM32G030xx devices vector table for MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the CortexM0 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.
