NAND Flash signals
Figure 14-5. NAND Flash Signal Multiplexing on EBI Pins
The address latch enable and command latch enable signals on the NAND Flash device are
driven by address bits ADDR[22] and ADDR[21] of the EBI address bus. The user should note
that any bit on the EBI address bus can also be used for this purpose. The command, address or
data words on the data bus of the NAND Flash device are distinguished by using their address
within the NCSx address space. The chip enable (CE) signal of the device and the ready/busy
(R/B) signals are connected to I/O Controller lines. The CE signal then remains asserted even
when NCSx is not selected, preventing the device from returning to standby mode.

Note:
The External Bus Interfaces is also able to support 16-bits devices.
