How to use BSDL Files :
=======================

The STM32L4 MCUs integrate two serially connected JTAG TAPs, the boundary scan
TAP (IR is 5-bit wide) and the CortexMx TAP (IR is 4-bit wide).

The package contains :

   + A BSDL File for the CortexMx TAP and is common to all STM32L4xxx  devices
   + Boundary scan BSDL Files for each stm32l471_475_476_486 device on different packages :
	  o LQFP100
	  o LQFP64
	  
   + Boundary scan BSDL Files for each stm32l471_476_486 device on different packages :
	  o LQFP144
	  o UFBGA132

   + Boundary scan BSDL Files for each stm32l471_476 device on different packages :
	  o UFBGA144

   + Boundary scan BSDL Files for each stm32l476_486 device on different packages :
	  o WLCSP72

   + Boundary scan BSDL Files for each stm32l476 device on different packages :
	  o WLCSP81

   + Boundary scan BSDL Files for each stm32l476_l486_P device on different packages :
	  o LQFP144
	  o LQFP64	  
	  o UFBGA132
	  o WLCSP72

   + Boundary scan BSDL Files for each stm32l431_433_443 device on different packages :
	  o LQFP100
	  o LQFP64
	  o LQFP48
	  o UFQFPN48
	  o UFBGA100
	  o UFBGA64
	  o WLCSP64
	  o WLCSP49

   + Boundary scan BSDL Files for each stm32l431_432_442 device on different packages :
          o UFQFPN32


   + BSDL File for stm32l433_P device on different packages : 
	  o LQFP64 

   + Boundary scan BSDL Files for each stm32l496_4a6 device on different packages :
	  o LQFP144
	  o LQFP100
	  o LQFP64
	  o UFBGA169
	  o UFBGA132
	  o WLCSP100

   + Boundary scan BSDL Files for each stm32l496_l4a6_P device on different packages :
	  o LQFP144
	  o UFBGA169
	  o UFBGA132
	  o WLCSP100

   + Boundary scan BSDL Files for each STM32L451_452_462 device on different packages :
	  o LQFP100
	  o LQFP64
	  o UFBGA100
	  o UFBGA64
	  o WLCSP64
	  o UFQFPN48
	  o LQFP48
	  

   + Boundary scan BSDL Files for each STM32L452_P device on package :
	  o LQFP64
	  o WLCSP64

   + Boundary scan BSDL Files for each STM32L412_422 device on different packages :
	  o LQFP64
          o LQFP48
          o LQFP32
	  o UFBGA64
	  o UFQFPN48
	  o UFQFPN32
	  o WLCSP36

   + Boundary scan BSDL Files for each STM32L412_422_P device on package :
	  o LQFP64

In order to run boundary scan, always provide two BSDL files to your JTAG Boundary scan tool:
the "CortexMx.bsd" and your selected "STM32xx_device_Package.bsd".  

WARNING : Do not combine both BSDL files in a single TAP with 9-bit wide !

For more details on the internal TAPs description refer to the Reference Manual
of the selected STM32xxxx device , Section : JTAG TAP connection.
