+IBM POWER9 LPC (low pin count) traffic
+-------------------------------------------------------------------------------
+
+These captures are examples of various transaction types from an IBM POWER9 LPC
+(low pin count) interface.
+
+Details:
+http://en.wikipedia.org/wiki/Low_Pin_Count
+
+
+Hardware setup
+--------------
+
+The logic analyser used was a DreamSourceLab DSLogic U3Pro32. As support for
+this is not yet in sigrok, the traces were captured externally and imported.
