PC Card/CompactFlash controller waveforms and timings

Figure 64 through Figure 69 represent synchronous waveforms together with Table 80 and

Table 81 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.

td(CLKL-Data) FSMC_D[15:0] valid data after FSMC_CLK low

td(CLKL-NBLH) FSMC_CLK low to FSMC_NBL high

1. CL = 30 pF.

2. Based on characterization, not tested in production.
