72 / 123 page ![]() Electrical characteristics STM32F103xC, STM32F103xD, STM32F103xE 72/123 Doc ID 14611 Rev 7 PC Card/CompactFlash controller waveforms and timings Figure 32 through Figure 37 represent synchronous waveforms and Table 39 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; Figure 32.
