Atmel-6249N-ATARM-SAM9263-Datasheet_14-Mar-16
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. EBI0 signals only
4. EBI1 signals only
5. 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 either connected to NCS3/NANDCS or to any free PIO line.
6. I/O8–I/O15 pins used only for 16-bit NAND Flash device.
7. EBI0_NWAIT signal is multiplexed with PD5. EBI1_NWAIT signal is multiplexed with PE20.
