Notes to
(1) Connect the pull-up resistors to the V
(2) Connect the pull-up resistor to the V
(3) 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.
(4) The MSEL pin settings vary for different configuration voltage standards and POR time. You must set the master device in AS mode and the slave
(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 for DATA[0] and DCLK. All I/O inputs must maintain a maximum AC voltage
(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.
