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

Equation 8–1 on page 8–5

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

or

, in which each of the

CONF_DONE

and

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.

Notes to

Figure 8–26

(1) Connect these pull-up resistors to the V

CCIO

supply of the bank in which the pin resides.

(2) Connect the

nCONFIG

and

MSEL

pins to support a non-JTAG configuration scheme. If you only use a JTAG configuration, connect the

nCONFIG

pin to logic-high and the

MSEL

pins to GND. In addition, pull

DCLK

and

DATA[0]

to either high or low, whichever is convenient on your board.

(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

CC

of the ByteBlaster II or USB-Blaster cable with supply from V

CCIO

. The ByteBlaster II and USB-Blaster cables do not support a

target supply voltage of 1.2 V. For the target supply voltage value, refer to the
