Notes to
(1) Connect the pull-up resistors to the V
(2) Connect the pull-up resistor to the V
(3) You can leave the nCEO pin unconnected or use it 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. You must set the master device of the Cyclone IV device
(5) Connect the series resistor at the near end of the serial configuration device.
(6) Connect the repeater buffers between the master and slave devices of the Cyclone IV device for DATA[0] and DCLK. All I/O inputs must maintain
(7) The 50- series resistors are optional if the 3.3-V configuration voltage standard is applied. For optimal signal integrity, connect these 50- series
(8) 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
(9) Only Cyclone IV GX devices have an option to select CLKUSR (40 MHz maximum) as the external clock source for DCLK.

The first Cyclone IV device in the chain is the configuration master and it controls the
configuration of the entire chain. Other Altera devices that support PS configuration
can also be part of the chain as configuration slaves.
In the multi-device AS configuration, the board trace length between the serial
configuration device and the master device of the Cyclone IV device must follow the
