1. Not directly connected to the CompactFlash slot. Permits the control of the bidirectional buffer between the EBI data bus and
2. Any PIO line.
3. CE connection depends on the NAND Flash.
4. I/O8 - !/O15 pins used only for 16-bit NANDFlash device.
5. EBI_NWAIT signal is multiplexed with PC15.

the CompactFlash slot.
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 either connected to NCS3/NANDCS or to any free PIO line.
