The nCEO pin can be left unconnected or used as a user I/O pin when it does not feed another device’s nCE pin.
The MSEL pin settings vary for different configuration voltage standards and POR time. You must set the
Cyclone III master device in AP mode and the slave devices in FPP mode. To connect MSEL[3..0] for the master
device in AP mode, refer to

The current implementation for AP configuration ignores the RDY pin. However it is recommended that you connect
this pin.
Connect the repeater buffers between the Cyclone III master and slave device(s) for DATA[15..0] and DCLK. All
I/O inputs must maintain a maximum AC voltage of 4.1V. The output resistance of the repeater buffers has to fit the
maximum overshoot equation outlined in

Byte-Wide Multi-Device AP Configuration
The first method is the byte-wide multi-device AP configuration and is
the simpler form. In the byte-wide multi-device AP configuration, the
least significant byte DATA[7..0] from the flash and master device set
to AP configuration scheme is connected to each of the slave devices set
to FPP configuration scheme, as shown in
