If AEQ_EN = 0, this field selects EQ for USB3.1 RX2 receiver which faces the USB-C receptacle. When EQ_OVERRIDE = 0b, this field reflects the sampled state of EQ[1:0] pins. When EQ_OVERRIDE = 1b, software can change the EQ setting for RX2p/n pins based on value written to this field. When AEQ_EN = 1 and AEQ_MODE = x0, selects EQ setting for USB downstream facing port1 (RX2) when short channel is detected. Value programmed into this field should provide best Rx JTOL results for short channel configuration.
