Arria II GX Device Handbook, Volume 1
You can set a lower clock frequency by specifying a division factor in the Quartus II
software (refer to
where n is between 1 and 8. The divisor ranges from 2 through 256 (refer to
Equation
Equation 10–1.
The error message register is updated whenever an error occurs. If the error location
and message are not shifted out before the next error location is found, the previous
error location and message is overwritten by the new information. To avoid this, you
must shift these bits out within one frame CRC verification. The minimum interval
time between each update for the error message register depends on the device and
the error detection clock frequency. However, slowing down the error detection clock
frequency slows down the error recovery time for the SEU event.

The error detection frequency reflects the frequency of the error detection
process for a frame because the CRC calculation in Arria II GX devices is
done on a per-frame basis.
