Abstract
A method is described. The method includes receiving from a memory controller configuration information for a testing sequence and storing the configuration information in configuration register space of the driver circuit. The method also includes controlling the next testing sequence. The testing sequence includes sweeping values of a tap coefficient of a DFE circuit of the driver circuit and sweeping a voltage of a slicer of the driver circuit. The method includes sending results of the testing sequence to the memory controller. The results are to determine a value for the DFE tap coefficient.
