FSMC characteristics

Asynchronous waveforms and timings

Figure 54 through Figure 57 represent asynchronous waveforms and Table 67 through

Table 70 provide the corresponding timings. The results shown in these tables are obtained

with the following FSMC configuration:

●

AddressSetupTime = 0

●

AddressHoldTime = 1

●

DataSetupTime = 1
