The address latch enable and command latch enable signals on the NAND Flash device are
driven by address bits A22 and A21 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
NCS3 address space. The chip enable (CE) signal of the device and the ready/busy (R/B) sig-
nals are connected to PIO lines. The CE signal then remains asserted even when NCS3 is not
selected, preventing the device from returning to standby mode.
