The same set of base ATA/IDE signals are common to each of the ATA/IDE interfaces, as well as the Compact Flash card reader. As such, only one of these interfaces may be used from an FPGA design – they can not be used concurrently. In Figure 1 above, the block diagram is drawn to show use of the 3.5" ATA/IDE interface.
