Description

Function L1 Control Register 1

Fields

L1RESPEN

L1 Response Enable

0 (0): LPM is not supported.

1 (1): LPM is supported.

L1RESPMD

L1 Response Mode

0 (00): NYET

1 (01): ACK

2 (10): STALL

3 (11): According to the L1NEGOMD bit

L1NEGOMD

L1 Response Negotiation Control.NOTE: This bit is valid only when the L1RESPMD[1:0] value is 2’b11.

0 (0): When receive HIRD is larger than HIRDTHR[3:0], ACK response is returned. In other cases (including HIRD = HIRDTHR[3:0]), NYET response is returned.

1 (1): When receive HIRD is smaller than HIRDTHR[3:0], ACK response is returned. In other cases (including HIRD = HIRDTHR[3:0]), NYET response is returned.

DVSQ

DVSQ Extension.DVSQ[3] is Mirror of DVSQ[2:0] in INTSTS0.Indicates the L1 state together with the device state bits DVSQ[2:0].

0 (others): setting prohibited

0 (0000): Powered state

1 (0001): Default state

2 (0010): Address state

3 (0011): Configured state

4 (0100): Suspended state

5 (0101): Suspended state

6 (0110): Suspended state

7 (0111): Suspended state

8 (1000): L1 state

9 (1001): L1 state

10 (1010): L1 state

11 (1011): L1 state

HIRDTHR

L1 Response Negotiation Threshold ValueHIRD threshold value used for L1NEGOMD.The format is the same as the HIRD field in HL1CTRL.

L1EXTMD

PHY Control Mode at L1 Return

0 (0): SUSPENDM is not set by hardware when Host K is received.

1 (1): SUSPENDM is set by hardware when Host K is received.
