NAND controller waveforms and timings
Figure 35 through Figure 38 represent synchronous waveforms and Table 40 provides the
corresponding timings. The results shown in this table are obtained with the following FSMC
configuration:
● COM.FSMC_SetupTime = 0x01;
● COM.FSMC_WaitSetupTime = 0x03;
● COM.FSMC_HoldSetupTime = 0x02;
● COM.FSMC_HiZSetupTime = 0x01;
● ATT.FSMC_SetupTime = 0x01;
● ATT.FSMC_WaitSetupTime = 0x03;
● ATT.FSMC_HoldSetupTime = 0x02;
● ATT.FSMC_HiZSetupTime = 0x01;
● Bank = FSMC_Bank_NAND;
● MemoryDataWidth = FSMC_MemoryDataWidth_16b;
● ECC = FSMC_ECC_Enable;
● ECCPageSize = FSMC_ECCPageSize_512Bytes;
● TCLRSetupTime = 0;
● TARSetupTime = 0;
