Configuration
© December 2010 Altera Corporation
To ensure DCLK and DATA[0] are not left floating at the end of configuration, the
MAX II device must drive them either high or low, whichever is convenient on your
board. The DATA[0] pin is available as a user I/O pin after configuration. In the PS
scheme, the DATA[0] pin is tri-stated by default in user mode and must be driven by
the external host device. To change this default option in the Quartus II software,
select the Dual-Purpose Pins tab of the Device and Pin Options dialog box.
The configuration clock (DCLK) speed must be below the specified system frequency
to ensure correct configuration. No maximum DCLK period exists, which means you
can pause configuration by halting DCLK for an indefinite amount of time.
The external host device can also monitor CONF_DONE and INIT_DONE to ensure
successful configuration. The CONF_DONE pin must be monitored by the external
device to detect errors and to determine when programming is complete. If all
configuration data is sent, but CONF_DONE or INIT_DONE has not gone high, the
external device must reconfigure the target device.

This circuit is similar to the PS configuration circuit for a single device, except that
Cyclone IV devices are cascaded for multi-device configuration.

(3) The nCEO pin is left unconnected or used as a user I/O pin when it does not feed the nCE pin of another device.
(4) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect the MSEL pins,
