Compact Flash Controller

Hello, I'am working on a project that consists in making a Compact Flash Controller for a specific microprocessor (Verilog). I've found some documents about this subject, but I'm still in doubt...

Hi,

Basically compact flash card can be used in different mode like Ture IDE PIO mode, DMA mode.

Out of 50 Pins some of the pins are not used in while you are using CF card in True IDE PIO mode. You have to keep pins as ground/VCC.

You have to take care of timing of address/read/write signals coming from CPU when you want to pass them to CF card. Before do read/write to CF card you have set CF's register like cylinder no, sector no, etc..
