+;* File Name : startup_stm32g051xx.s
+;* Author : MCD Application Team
+;* Description : STM32G051xx 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
+;* - Branches to main in the C library (which eventually
+;* calls main()).
+;* After Reset the Cortex-M0+ processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.

+;******************************************************************************
+;* File Name : startup_stm32g0b0xx.s
+;* Author : MCD Application Team
+;* Description : STM32G0B0xx 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
+;* - Branches to main in the C library (which eventually

+;* After Reset the Cortex-M0+ processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.

+;******************************************************************************
+;* File Name : startup_stm32g0b1xx.s
+;* Author : MCD Application Team
+;* Description : STM32G0B1xx 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
+;* - Branches to main in the C library (which eventually
+;* calls main()).
+;* After Reset the Cortex-M0+ processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.

+;******************************************************************************
+;* File Name : startup_stm32g0c1xx.s
+;* Author : MCD Application Team
+;* Description : STM32G0C1xx 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
+;* - Branches to main in the C library (which eventually
+;* calls main()).
+;* After Reset the Cortex-M0+ processor is in Thread mode,
+;* priority is Privileged, and the Stack is set to Main.
