Bit Field Type Reset Description
7 CM_ACTIVE R/U 0 0 –device not in USB 3.1 compliance mode. (Default)
1 –device in USB 3.1 compliance mode
6 LFPS_EQ R/W 0 Controls whether settings of EQ based on EQ1_SEL, EQ2_SEL and SSEQ_SEL applies to received LFPS signal.
0 – EQ set to zero when receiving LFPS (default)
1 – EQ set to EQ1_SEL, EQ2_SEL, and SSEQ_SEL when receiving LFPS.
5 U2U3_LFPS_DEBOUNCE R/W 0 0 – No debounce of LFPS before U2/U3 exit. (Default)
1 – 200 µs debounce of LFPS before U2/U3 exit.
4 DISABLE_U2U3_RXDET R/W 0 0 – Rx.Detect in U2/U3 enabled. (Default)
1 – Rx.Detect in U2/U3 disabled.
3:2 DFP_RXDET_INTERVAL R/W 01 This field controls the Rx.Detect interval for the Downstream facing port (TX1P/N and TX2P/N).
00 – 8 ms
01 – 12 ms (default)
10 – 48 ms
11 – 96 ms
1:0 USB3_COMPLIANCE_CTRL R/W 00 00 – FSM determined compliance mode. (Default)
01 – Compliance Mode enabled in DFP direction (SSTX -> TX1/TX2)
10 – Compliance Mode enabled in UFP direction (RX1/RX2 -> SSRX)
11 – Compliance Mode Disabled.
