+                        ##### 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. 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)
+           (++) Read-only memory (ROM)
+           (++) NOR Flash memory/OneNAND 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
