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-kΩ resistor.
This pin, when driven low by the Arria II device, indicates
that the device has encountered an error during
configuration.

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 V
devices are 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-kΩ pull-up
resistor for the device to initialize.
Driving CONF_DONE low after configuration and initialization
does not affect the configured device.
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.

buffer 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
did not yet trip. When POR trips after V
powered up, nSTATUS is released and pulled high. At that
point, reconfiguration is triggered and the device is
configured.
