The address latch enable and command latch enable signals on the NAND Flash/SmartMedia
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/SmartMedia 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) signals 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. Some func-
tional limitation with the supported burst Flash device will occur when the NAND
Flash/SmartMedia device is activated due to the fact that the SMOE and SMWE signals are mul-
tiplexed with BFRDY and BFBAA signals respectively.
