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

The STM32WL 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 CortexM4 TAP, common to all STM32WL devices
   + Boundary scan BSDL File for STM32WL_E5_E4_55_54 device on package :
   
	  o UFBGA73
	  o UFQFPN48
	  



In order to run boundary scan, always provide two BSDL files to your JTAG Boundary scan tool:
the "CortexMx.bsd" and your selected "STM32WLxx_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.

=========================
* V2.0 - 30-November-2020
=========================
  + Added package UFQFPN48 for STM32WL_E5_E4_55_54 devices.
=========================
* V1.0 - 20-december-2019
=========================
  Created with BSDL files for STM32WL device.
