Synchronous waveforms and timings
Figure 21 through Figure 24 represent synchronous waveforms and Table 42 through
Table 44 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;
●
DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
