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

Currently the RDY pin does not listen during configuration. 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
