PC Card/CompactFlash controller waveforms and timings

Figure 62 through Figure 67 represent synchronous waveforms and Table 75 provides the

corresponding timings. The results shown in this table are obtained with the following FSMC

configuration:

●

COM.FSMC_SetupTime = 0x04;

●

COM.FSMC_WaitSetupTime = 0x07;

●

COM.FSMC_HoldSetupTime = 0x04;

●

COM.FSMC_HiZSetupTime = 0x00;

●

ATT.FSMC_SetupTime = 0x04;

●

ATT.FSMC_WaitSetupTime = 0x07;

●

ATT.FSMC_HoldSetupTime = 0x04;

●

ATT.FSMC_HiZSetupTime = 0x00;

●

IO.FSMC_SetupTime = 0x04;

●

IO.FSMC_WaitSetupTime = 0x07;

●

IO.FSMC_HoldSetupTime = 0x04;

●

IO.FSMC_HiZSetupTime = 0x00;

●

TCLRSetupTime = 0;

●

TARSetupTime = 0;
