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 III device
(5) These are dual-purpose I/O pins. The nCSO pin functions as the FLASH_NCE pin in AP mode. The ASDO pin functions as the DATA[1] pin in
(6) Connect the series resistor at the near end of the serial configuration device.
(7) Connect the repeater buffers between the master and slave devices of the Cyclone III device family for DATA[0] and DCLK. All I/O inputs must
