Why does the UniPHY CORDROP_ERROR register show a non-zero value?

Description

Why does the UniPHY CORDROP_ERROR register show a non-zero value?

Resolution

When you have ECC enabled with Auto Correction in your DDR3 UniPHY memory controller, you may see that the UniPHY Auto Correction Drop (CORDROP_ERROR) register contains a non-zero value. This register will increment when the error address FIFO in the controller is full, and the controller cannot schedule an auto-correction command.
