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 ISP1504 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 ISP1504 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.

Command description
No operation. 00h is the idle value of the data bus. The
link must drive NOOP by default.
Transmit USB data that does not have a PID, such as
chirp and resume signaling. The ISP1504 starts
transmitting only after accepting the next data byte.
Transmit USB packet. DATA[3:0] indicates USB packet
identifier PID[3:0].
Extended register write command (optional). The 8-bit
address must be provided after the command is
accepted.
Register write command with 6-bit immediate address.
Extended register read command (optional). The 8-bit
address must be provided after the command is
accepted.
Register read command with 6-bit immediate address.
