Notes to
(1) Connect the pull-up resistors to the 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. You must set the master device of the Cyclone IV device
(4) Connect the series resistor at the near end of the serial configuration device.
(5) Connect the repeater buffers between the master and slave devices for DATA[0] and DCLK. All I/O inputs must maintain a maximum AC voltage
(6) The 50- series resistors are optional if the 3.3-V configuration voltage standard is applied. For optimal signal integrity, connect these 50- series
(7) These pins are dual-purpose I/O pins. The nCSO pin functions as FLASH_nCE pin in AP mode. The ASDO pin functions as DATA[1] pin in AP
(8) Only Cyclone IV GX devices have an option to select CLKUSR (40 MHz maximum) as the external clock source for DCLK.

The second method configures both the master device and slave devices with the
same .sof. The serial configuration device stores one copy of the .sof. You must set up
one or more slave devices in the chain. All the slave devices must be set up in the
same way
In this setup, all the Cyclone IV devices in the chain are connected for concurrent
configuration. This reduces the AS configuration time because all the Cyclone IV
devices are configured in one configuration cycle. Connect the nCE input pins of all
the Cyclone IV devices to GND. You can either leave the nCEO output pins on all the
Cyclone IV devices unconnected or use the nCEO output pins as normal user I/O
pins. The DATA and DCLK pins are connected in parallel to all the Cyclone IV devices.
