PC Card/CompactFlash controller waveforms and timings
Figure 30 through Figure 35 represent synchronous waveforms and Ta ble 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;
