8.5.3.1. XCVR_A10_RX_ADP_DFE_FXTAP
Description
The following assignments specify the coefficient of DFE fixed taps 1 through 11. These assignments are applicable only when the DFE is enabled and adaptation is disabled for the DFE (DFE operates in manual mode). The default value for all assignments is set to RADP_DFE_FXTAP<1 to 11>_0 for DFE fixed tap<1 to 11> coefficient setting 0. DFE tap1 in the only tap which is always positive and hence there is no QSF assignment for DFE tap1 sign bit. Other taps can be positive or negative.
