The MSEL[2..0] pins have internal 5-kΩ pull-down
resistors that are always active.
Configuration control input. Pulling this pin low during
user-mode causes the device to lose its configuration data,
enter a reset state, and tri-state all I/O pins. Returning this
pin to a logic high level initiates a reconfiguration.
Configuration is possible only if this pin is high, except in
JTAG programming mode, when nCONFIG is ignored.
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 Stratix IV 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 initiate a
reconfiguration, nCONFIG must be pulled low.
If you have enabled the Auto-restart configuration after
error option, the nSTATUS pin transitions from high to low
and back again to high when a configuration error is
detected. This appears as a low pulse at the pin with a
minimum pulse width of 10 μs to a maximum pulse width
of 500 μs, as defined in the t
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.
