FSMC characteristics
Asynchronous waveforms and timings
Figure 54 through Figure 57 represent asynchronous waveforms and Table 70 through
Table 73 provide the corresponding timings. The results shown in these tables are obtained
with the following FSMC configuration:
● AddressSetupTime = 1
● AddressHoldTime = 1
● DataSetupTime = 1
● BusTurnAroundDuration = 0x0
In all timing tables, the T_HCLK is the HCLK clock period.
