PS Configuration Using an External Host
In the PS configuration scheme, you can use an intelligent host such as MAX II or
microprocessor that controls the transfer of configuration data from a storage device,
such as flash memory, to the target Cyclone III device family. You can store the
configuration data in .rbf, .hex, or .ttf format.

Notes to
(1) Connect the pull-up resistor to a supply that provides an acceptable input signal for the device. V
(2) 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.
(3) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL[3..0],
(4) All I/O inputs must maintain a maximum AC voltage of 4.1 V. DATA[0] and DCLK must fit the maximum overshoot
To begin configuration, the external host device must generate a low-to-high
transition on the nCONFIG pin. When nSTATUS is pulled high, the external host
device must place the configuration data one bit at a time on the DATA[0]pin. If you
are using configuration data in a .rbf, .ttf, or .hex file, you must first send the LSB of
each data byte. For example, if the .rbf contains the byte sequence 02 1B EE 01 FA, the
serial bitstream you must send to the device is:
Cyclone III device family receives configuration data on the DATA[0]pin and the
clock is received on the DCLK pin. Data is latched into the device on the rising edge of
DCLK. Data is continuously clocked into the target device until CONF_DONE goes high
and the device enters the initialization state.
Two DCLK falling edges are required after CONF_DONE goes high to begin device
initialization.
The INIT_DONE pin is released and pulled high when initialization is complete. The
external host device must be able to detect this low-to-high transition which signals
the device has entered user mode. When initialization is complete, the device enters
user mode. In user mode, the user I/O pins no longer have weak pull-up resistors and
function as assigned in your design.
