5. In the Device and Pin Options dialog box, click the Error Detection CRC tab.
6. Turn on Enable error detection CRC

7. In the Divide error check frequency by pull-down list, enter a valid divisor as
The divide value divides the frequency of the configuration oscillator output clock
that clocks the CRC circuitry.
8. Click OK.
The system that the Stratix IV device resides in must control device reconfiguration.
After detecting an error on the CRC_ERROR pin, strobing the nCONFIG signal low directs
the system to perform the reconfiguration at a time when it is safe for the system to
reconfigure the device.
When the data bit is rewritten with the correct value by reconfiguring the device, the
device functions correctly.
While soft errors are uncommon in Altera devices, certain high-reliability applications
require a design to account for these errors.
