                      ##### 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.
