NAND controller waveforms and timings
Figure 71 through Figure 74 represent synchronous waveforms, together with Table 82 and
Table 83 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;
In all timing tables, the T
HCLK
is the HCLK clock period.
