;* File Name : startup_stm32f303x8.s
;* Author : MCD Application Team
;* Version : $VERSION$
;* Date : 12-Sept-2014
;* Description : STM32F303x6/x8 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 CortexM4 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

;* Version : V1.2.2
;* Date : 27-February-2015
;* Description : STM32F303xE 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 CortexM4 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

;/******************** (C) COPYRIGHT 2015 STMicroelectronics ********************
;* File Name : startup_stm32l100xc.s
;* Author : MCD Application Team
;* Version : V2.1.2
;* Date : 09-October-2015
;* Description : STM32L100XC Devices vector 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.
;* - Configure the system clock
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the Cortex-M3 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

Examples
========
All examples build upon the `main_example.asm` provided here - it's the basic boilerplate.
To avoid duplication, the `Delay.asm` file here is shared by all the examples.
The `Makefile`s in the example projects work with KEIL installed in Wine.
If you are using KEIL on Windows, create a new project and copy the `.asm` and `.s` files into it.
