8.4.3. EMR Update Interval

You must unload the EMR data within the minimum EMR Update Interval to avoid the current EMR data from being overwritten by the information of the next error. However, EMR Unloader IP core can handle this by monitoring no EMR data loss during unloading process. The IP core detects the loss of EMR information by flagging the emr_error signal.

The interval between each update of the error message register depends on the device and the frequency of the error detection clock.

Note: For Cyclone® 10 GX devices, the EMR update interval time is 0.28 ms and N equals 2 or 4 only.
