c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	14 This driver is a generic layered driver which contains a set of APIs used to
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	15 control SDRAM memories. It uses the FMC layer functions to interface
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	16 with SDRAM devices.
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	17 The following sequence should be followed to configure the FMC to interface
c78bcbd5deda Added current STM32 standandard libraries in version independend folder structure Ideenmodellierer parents: diff changeset	18 with SDRAM memories:
