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
