		4	; Description : STM32F103xB Devices vector table for MDK-ARM toolchain.*
		5	; This module performs:*
		6	; - Set the initial SP*
		7	; - Set the initial PC == Reset_Handler*
		8	; - Set the vector table entries with the exceptions ISR address*
		9	; - Configure the clock system*
		10	; - Branches to __main in the C library (which eventually*
		11	; calls main()).*
		12	; After Reset the Cortex-M3 processor is in Thread mode,*
		13	; priority is Privileged, and the Stack is set to Main.*
