6.3.24
Embedded reference voltage
The parameters given in Table 71 are derived from tests performed under ambient
temperature and VDD supply voltage conditions summarized in Table 14.
6.3.25
FSMC characteristics
Asynchronous waveforms and timings
Figure 56 through Figure 59 represent asynchronous waveforms and Table 72 through
Table 75 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 THCLK is the HCLK clock period.
