CompactFlash is a flash memory with an embedded controller that makes it look very much like an IDE device. In fact it has what's called True-IDE mode that makes it look exactly like a minature IDE disk. You read/write the disk using the 8 byte IDE task file and the 16 bit dta bus. The bus can programmatically be reduced to an 8 bit bus if you need to conserve pins.
