Return to Summary Table. Figure 32. DFP1_EQ Register 7 6 5 4 3 2 1 0 DTX1EQ_SEL DRX1EQ_SEL R/W-0h R/W-0h Table 21. DFP1_EQ Register Field Descriptions Bit Field Type Reset Description 7-4 DTX1EQ_SEL R/W 0h Field selects EQ for DTX1P/N pins. When EQ_OVERRIDE = 0b, this field reflects the sampled state of DEQ[1:0] pins. When EQ_OVERRIDE = 1b, software can change the EQ setting for DTX1P/N pins based on value written to this field. 3-0 DRX1EQ_SEL R/W 0h Field selects EQ for DRX1P/N pins. When EQ_OVERRIDE = 0b, this field reflects the sampled state of DEQ[1:0] pins. When EQ_OVERRIDE = 1b, software can change the EQ setting for DRX1P/N pins based on value written to this field. 7.6.1.11 USB3_MISC Register (Offset = 22h) [reset = 4h] USB3_MISC is shown in Figure 33 and described in Table 22. Return to Summary Table. Figure 33. USB3_MISC Register 7 6 5 4 3 2 1 0 CM_ACTIVE LFPS_EQ U2U3_LFPS_D EBOUNCE DISABLE_U2U 3_RXDET DFP_RXDET_INTERVAL USB_COMPLIANCE_CTRL RH-0h R/W-0h R/W-0h R/W-0h R/W-1h R/W-0h Table 22. USB3_MISC Register Field Descriptions Bit Field Type Reset Description 7 CM_ACTIVE RH 0h Compliance mode status. 0h = Not in USB3.1 compliance mode. 1h = In USB3.1 compliance mode. 6 LFPS_EQ R/W 0h Controls whether settings of EQ based on URX[2:1]EQ_SEL, UTX[2:1]EQ_SEL, DRX[2:1]EQ_SEL, and DTX[2:1]EQ_SEL applies to received LFPS signal. 0h = EQ set to zero when receiving LFPS 1h = EQ set by the related registers when receiving LFPS. 5 U2U3_LFPS_DEBOUNCE R/W 0h Controls whether or not incoming LFPS is debounced or not. 0h = No debounce of LFPS before U2/U3 exit. 1h = 200us debounce of LFPS before U2/U3 exit. 4 DISABLE_U2U3_RXDET R/W 0h Controls whether or not Rx.Detect is performed in U2/U3 state. 0h = Rx.Detect in U2/U3 enabled. 1h = Rx.Detect in U2/U3 disabled. 3-2 DFP_RXDET_INTERVAL R/W 1h This field controls the Rx.Detect interval for the downstream facing port (DTX1P/N and DTX2P/N). 0h = 8ms 1h = 12ms 2h = Reserved 3h = Reserved. |
