All External Memory Interface signals are 5 V tolerant.
All External Memory Interface outputs are high impedance while System Reset is LOW.
If the External Memory Interface is unused, all input pins may be left unconnected.
Active low signals are designated by a # suffix, in accordance with the convention used in common memory data
sheets.
