FSMC_NORSRAM_TimingTypeDef::DataLatency field

Defines the number of memory clock cycles to issue to the memory before getting the first data. The parameter value depends on the memory type as shown below: - It must be set to 0 in case of a CRAM - It is don't care in asynchronous NOR, SRAM or ROM accesses - It may assume a value between Min_Data = 2 and Max_Data = 17 in NOR Flash memories with synchronous burst mode enable
