+// PCIe.
+// =============================================================================
+// REVISION HISTORY
+// Version : 1.5
+// Author(s) : ES/EB
+// Mod. Date : March 21, 2017
+// Changes Made : 1. Added pdiff_sync signal to syncrhonize pcount_diff
+// : to sli_refclk.
+// : 2. Updated terminal count logic for PCIe 5G
+// : 3. Modified checking of pcount_diff in SLL state
+// : machine to cover actual count
+// : (from 16-bits to 22-bits)
+// =============================================================================
+// REVISION HISTORY
+// Version : 1.6
+// Author(s) : ES
+// Mod. Date : April 19, 2017
+// Changes Made : 1. Added registered lock and unlock signal from
+// pdiff_sync to totally decouple pcount_diff from
+// SLL state machine.
+// : 2. Modified LPCLK_TC_4 to 1:1 clock ratio when CPRI
+// is operating @ 4.9125Gbps data rate.
