Notes: 1. Not directly connected to the CompactFlash slot. Permits the control of the bidirectional buffer between the EBI data bus
and the CompactFlash slot.
2. Any PIO line.
3. CE connection depends on the NAND Flash. For standard NAND Flash devices, it must be connected to any free PIO line.
For “CE don’t care” NAND Flash devices, it can be connected to either NCS3/NANDCS or to any free PIO line.
