Synchronous waveforms and timings
through
represent synchronous waveforms and
through
provide the corresponding timings. The results shown in these tables are obtained
with the following FSMC configuration:

BurstAccessMode = FSMC_BurstAccessMode_Enable;
MemoryType = FSMC_MemoryType_CRAM;
WriteBurst = FSMC_WriteBurst_Enable;
CLKDivision = 1; (0 is not supported, see the STM32F10xxx reference manual)
DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
