Pin Type
The device drives nSTATUS low immediately after power up
and releases it after the POR time.
During user mode and regular configuration, this pin is pulled
high by an external 10-k resistor.
This pin, when driven low by the Arria II GX device, indicates
that the device has encountered an error during configuration.
Status output. If an error occurs during configuration,
nSTATUS is pulled low by the target device.
Status input. If an external source drives the nSTATUS pin
low during configuration or initialization, the target device
enters an error state.
Driving nSTATUS low after configuration and initialization
does not affect the configured device. If you use a
configuration device, driving nSTATUS low causes the
configuration device to attempt to configure the device, but
because the device ignores transitions on nSTATUS in user
mode, the device does not reconfigure. To begin a
reconfiguration, nCONFIG must be pulled low.
If the V
pin resides is not fully powered up, the following could occur:

Status output. The target device drives the CONF_DONE pin
low before and during configuration. After all configuration
data is received without error and the initialization cycle
starts, the target device releases CONF_DONE.
Status input. After all data is received and CONF_DONE goes
high, the target device initializes and enters user mode. The
CONF_DONE pin must have an external 10-k pull-up
resistor for the device to initialize.
Driving CONF_DONE low after configuration and initialization
does not affect the configured device.

is ramped up, POR trips and nSTATUS is released after
POR expires.

to function properly. In this situation, nSTATUS might
appear logic high, triggering a configuration attempt that
fails because POR did not yet trip. When V

triggered and the device is configured.
