  ==============================================================================
                        ##### FMC peripheral features #####
  ==============================================================================
  [..] The Flexible memory controller (FMC) includes following memory controllers:
       (+) The NOR/PSRAM memory controller
       (+) The NAND memory controller
       
  [..] The FMC functional block makes the interface with synchronous and asynchronous static
       memories and 16-bit PC memory cards. Its main purposes are:
       (+) to translate AHB transactions into the appropriate external device protocol.
       (+) to meet the access time requirements of the external memory devices.
   
  [..] All external memories share the addresses, data and control signals with the controller.
       Each external device is accessed by means of a unique Chip Select. The FMC performs
       only one access at a time to an external device.
       The main features of the FMC controller are the following:
        (+) Interface with static-memory mapped devices including:
           (++) Static random access memory (SRAM).
           (++) NOR Flash memory.
           (++) PSRAM (4 memory banks).
           (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
                data
        (+) Independent Chip Select control for each memory bank
        (+) Independent configuration for each memory bank
