Cyclone III Device Handbook, Volume 1
In the AS configuration scheme, the serial configuration device latches input and
control signals on the rising edge of DCLK and drives out configuration data on the
falling edge. Cyclone III device family drives out control signals on the falling edge of
DCLK and latch configuration data on the falling edge of DCLK.
In configuration mode, the Cyclone III device family enables the serial configuration
device by driving the nCSO output pin low, which connects to the nCS pin of the
configuration device. The Cyclone III device family uses the DCLK and DATA[1]pins
to send operation commands and read address signals to the serial configuration
device. The configuration device provides data on its DATA pin, which connects to the
DATA[0] input of the Cyclone III device family.
After all the configuration bits are received by the Cyclone III device family, it releases
the open-drain CONF_DONE pin, which is pulled high by an external 10-kΩ resistor.
Initialization begins only after the CONF_DONE signal reaches a logic-high level. All
AS configuration pins (DATA[0], DCLK, nCSO, and DATA[1]) have weak internal
pull-up resistors that are always active. After configuration, these pins are set as input
tri-stated and are driven high by weak internal pull-up resistors. The CONF_DONE pin
must have an external 10-kΩ pull-up resistor for the device to initialize.

Multi-Device AS Configuration
You can configure multiple Cyclone III device family using a single serial
configuration device. You can cascade multiple Cyclone III device family using the
chip-enable (nCE) and chip-enable-out (nCEO) pins. The first device in the chain must
have its nCE pin connected to GND. You must connect its nCEO pin to the nCE pin of
the next device in the chain. Use an external 10-kΩ pull-up resistor to pull the nCEO
signal high to its V
device captures all its configuration data from the bitstream, it drives the nCEO pin
low, enabling the next device in the chain. You can leave the nCEO pin of the last
device unconnected or use it as a user I/O pin after configuration if the last device in
the chain is a Cyclone III device family. The nCONFIG, nSTATUS, CONF_DONE, DCLK,
and DATA[0] pins of each device in the chain are connected
