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.
The ISP1506 communicates status information to the link by asserting DIR and sending
an RXCMD byte on the DATA bus. The RXCMD data byte format is given in
The ISP1506 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
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 ISP1506 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.
