LINESTATE[1:0] reflects the current state of DP and DM. Whenever the ISP1505 detects
a change in DP or DM, an RXCMD will be sent to the link with the new LINESTATE[1:0]
value. The value given on LINESTATE[1:0] depends on the setting of various registers.

which applies to host controllers. Dual-role devices must choose the correct table,
depending on whether it is in peripheral or host mode.
Description and value
LINESTATE signals: For a definition of LINESTATE, see
DATA0 — LINESTATE[0]
DATA1 — LINESTATE[1]

By default, this signal is not used and is not needed in typical designs. Optionally, the link can
enable the BVALID_RISE and/or BVALID_FALL bits in the Power Control register. Corresponding
changes in BVALID will cause an RXCMD to be sent to the link with the ALT_INT bit asserted.
