Refer to Section 7.3.15: I/O port characteristics for more details on the input/output alternate
function characteristics.
Asynchronous waveforms and timings
Figure 77 through Figure 79 represent asynchronous waveforms and Table 163 through
Table 170 provide the corresponding timings. The results shown in these tables are
obtained with the following FMC configuration:
•
AddressSetupTime = 0x1
•
AddressHoldTime = 0x1
•
DataSetupTime = 0x1 (except for asynchronous NWAIT mode , DataSetupTime = 0x5)
•
BusTurnAroundDuration = 0x0
•
Capacitive load CL = 30 pF
In all timing tables, the TKERCK is the fmc_ker_ck clock period.
