132 / 173 page ![]() Electrical characteristics STM32F21xxx 132/173 Doc ID 17050 Rev 8 PC Card/CompactFlash controller waveforms and timings Figure 61 through Figure 66 represent synchronous waveforms together with Table 77 and Table 78 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; In all timing tables, the THCLK is the HCLK clock period.
