2. For NAND Flash connection examples, refer to “NAND Flash Support on AT91SAM7SE Microcontrollers”, application note.
3. I/O8 - I/O15 bits used only for 16-bit NAND Flash.
4. Not directly connected to the CompactFlash slot. Permits the control of the bidirectional buffer between the EBI data bus and
5. NWR1 enables upper byte writes. NWR0 enables lower byte writes.
6. Any free PIO line.
7. CE connection depends on the Nand Flash.
the CompactFlash slot.
For standard Nand Flash devices, it must be connected to any free PIO line.
For “CE don’t care” 8-bit Nand Flash devices, it can be either connected to NCS3/NANDCS or to any free PIO line.
For “CE don’t care” 16-bit Nand Flash devices, it must be connected to any free PIO line.
