Active-low chip enable. The nCE pin activates the device with
a low signal to allow configuration. The nCE pin must be held
low during configuration, initialization, and user mode. In
single device configuration, it must be tied low. In
multi-device configuration, nCE of the first device is tied low
while its nCEO pin is connected to nCE of the next device in
the chain.
The nCE pin must also be held low for successful JTAG
programming of the device.
Output that drives low when device configuration is complete.
In single-device configuration, this pin is left floating. In
multi-device configuration, this pin feeds the next device’s
nCE pin and is pulled high by an external 10-k  resistor. The
nCEO of the last device in the chain is left floating.
The nCEO pin is powered by the V
bank in which the nCEO pin resides.
After configuration, nCEO is available as user I/O pins. The
state of the nCEO pin depends on the Dual-Purpose Pin
settings.
Control signal from the Arria II GX device to the serial
configuration device in AS mode used to read out
configuration data.
In AS mode, ASDO has an internal pull-up resistor that is
always active.
Output control signal from the Arria II GX device to the serial
configuration device in AS mode that enables the
configuration device.
In AS mode, nCSO has an internal pull-up resistor that is
always active.
In PS and FPP configuration, DCLK is the clock input used to
clock data from an external source into the target device. Data
is latched into the device on the rising edge of DCLK.
In AS mode, DCLK is an output from the Arria II GX device
that provides timing for the configuration interface. In AS
mode, DCLK has an internal pull-up resistor (typically 25 k)
that is always active.
After configuration, this pin by default is driven into an
inactive state. In schemes that use a control host, DCLK must
be driven either high or low, whichever is more convenient.
Toggling this pin after configuration does not affect the
configured device.
