Synchronous waveforms and timings

Figure 58 through Figure 61 represent synchronous waveforms and Table 76 through

Table 78 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 STM32F20xxx/21xxx reference manual)

•

DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM

In all timing tables, the THCLK is the HCLK clock period.
