PC Card/CompactFlash controller waveforms and timings

Figure 30 through Figure 35 represent synchronous waveforms and Table 42 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;
