+                      ##### RCC Limitations #####
+  ==============================================================================
+    [..]
+      A delay between an RCC peripheral clock enable and the effective peripheral
+      enabling should be taken into account in order to manage the peripheral read/write
+      from/to registers.
+      (+) This delay depends on the peripheral mapping.
+        (++) AHB & APB peripherals, 1 dummy read is necessary
+
+    [..]
+      Workarounds:
+      (#) For AHB & APB peripherals, a dummy read to the peripheral register has been
+          inserted in each LL_{BUS}_GRP{x}_EnableClock() function.
