changes in BVALID will cause an RXCMD to be sent to the link with the ALT_INT bit asserted.
LINESTATE[1:0] reflects the current state of DP and DM. Whenever the ISP1504x1
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.
