Notes to
(1) Connect these pull-up resistors to the V
(2) Connect the nCONFIG and MSEL pins to support a non-JTAG configuration scheme. If you only use a JTAG configuration, connect the nCONFIG
(3) In the USB-Blaster and ByteBlaster II cable, this pin is connected to nCE when it is used for AS programming, otherwise it is a no connect.
(4) You must connect the nCE pin to GND or driven low for successful JTAG configuration.
(5) Power up the V

If a non-Cyclone IV device is cascaded in the JTAG-chain, TDO of the non-Cyclone IV
device driving into TDI of the Cyclone IV device must fit the maximum overshoot
outlined in
The CONF_DONE and nSTATUS signals are shared in multi-device AS, AP, PS, and FPP
configuration chains to ensure that the devices enter user mode at the same time after
configuration is complete. When the CONF_DONE and nSTATUS signals are shared
among all the devices, you must configure every device when JTAG configuration is
performed.
If you only use JTAG configuration, Altera recommends that you connect the circuitry
as shown in
nSTATUS signals are isolated so that each device can enter user mode individually.
After the first device completes configuration in a multi-device configuration chain,
its nCEO pin drives low to activate the nCE pin of the second device, which prompts
the second device to begin configuration. Therefore, if these devices are also in a JTAG
chain, ensure that the nCE pins are connected to GND during JTAG configuration or
that the devices are JTAG configured in the same order as the configuration chain. As
long as the devices are JTAG configured in the same order as the multi-device
configuration chain, the nCEO of the previous device drives the nCE pin of the next
device low when it has successfully been JTAG configured. You can place other Altera
devices that have JTAG support in the same JTAG chain for device programming and
configuration.
