+
+
+The Cortex Microcontroller Software Interface Standard (CMSIS) provides a single standard across all 
+Cortex-Mx processor series vendors. It enables code re-use and code sharing across software projects 
+and reduces time-to-market for new embedded applications.
+
+CMSIS is released under the terms of the end user license agreement ("CMSIS END USER LICENCE AGREEMENT.pdf").
+Any user of the software package is bound to the terms and conditions of the end user license agreement.
+
+
+You will find the following sub-directories:
+
