By default, this signal is not used and is not needed in typical designs. Optionally, the link can enable
the BVALID_RISE bit, the BVALID_FALL bit, or both in the PWR_CTRL register (see

the ALT_INT bit asserted.
The ISP1507D1 will automatically send an RXCMD whenever there is a change in any of
the RXCMD data fields. The link must be able to accept an RXCMD at any time; including
single RXCMDs, back-to-back RXCMDs, and RXCMDs at any time during USB receive
packets when NXT is LOW. An example is shown in
refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
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 ISP1507D1
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.
