Set to the value of the ID pin.
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.
An RXCMD may not be sent when exiting low-power mode or serial mode, if the interrupt
condition is removed before exiting.
LINESTATE[1:0] reflects the current state of DP and DM. Whenever the ISP1504 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.
