Notes to
(1) Connect the pull-up resistors to the V
(2) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL for AS
(3) Pin 6 of the header is a V
(4) You must connect the nCE pin to GND or driven low for successful JTAG configuration.
(5) 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.
(6) Power up the V
(7) Connect the series resistor at the near end of the serial configuration device.
(8) These pins are dual-purpose I/O pins. The nCSO pin functions as FLASH_nCE pin in AP mode. The ASDO pin
(9) Resistor value can vary from 1 k to 10 k..
(10) Only Cyclone IV GX devices have an option to select CLKUSR (40 MHz maximum) as the external clock source for
ISP of the Configuration Device
In the second stage, the SFL design in the master device allows you to write the
configuration data for the device chain into the serial configuration device with the
Cyclone IV device JTAG interface. The JTAG interface sends the programming data
for the serial configuration device to the Cyclone IV device first. The Cyclone IV
device then uses the ASMI pins to send the data to the serial configuration device.

the MSEL pins directly to V

ByteBlasterMV download cable, this pin is a no connect. When using USB-Blaster, ByteBlaster II, and EthernetBlaster
cables, this pin is connected to nCE when it is used for AS programming, otherwise it is a no connect.
Third-party programmers must switch to 2.5 V. Pin 4 of the header is a V
The MasterBlaster cable can receive power from either 5.0- or 3.3-V circuit boards, DC power supply, or 5.0 V from
the USB cable. For this value, refer to the
functions as DATA[1] pin in AP and FPP modes.
