NAND controller waveforms and timings
Figure 30 through Figure 33 represent synchronous waveforms, and Table 75 and Table 76 
provide the corresponding timings. The results shown in this table are obtained with the 
follow
ing FMC configuration:
• COM.FMC_S
etupTime = 0x01
• COM.FMC_WaitSetupTime = 0x03
• COM.FMC_HoldSetupTime = 0x02
• COM.FMC_HiZSetupTime = 0x01
• ATT.FMC_SetupTime = 0x01
• ATT.FMC_WaitSetupTime = 0x03
• ATT.FMC_HoldSetupTime = 0x02
• ATT.FMC_HiZSetupTime = 0x01
• Bank = FMC_Bank_NAND
• MemoryDataWidth = FMC_MemoryDataWidth_16b
• ECC = FMC_ECC_Enable
• ECCPageSize = FMC_ECCPageSize_512Bytes
• TCLRSetupTime = 0
• TARSetupTime = 0
• C
L
 = 30 pF
In all timing tables, the 
T
fmc_ker_ck
 is the fmc_ker_ck clock period.
