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.
