This signal senses the state of the USB ID signal.
The USB PHY enables an integrated pull-up, and
an external element (USB connector) indicates the
initial state of the USB controller (pulled down is
the A side of the cable and pulled up is the B side).
Asserted by the external PHY to throttle all data
types.
Optionally used in Host mode by an external power
source to indicate an error state by that power
source.
Asserted by the USB controller to signal the end of
a USB transmit packet or register write operation.
This signal is used during the session request
protocol. This signal allows the USB PHY to both
sense the voltage level of VBUS, and pull up VBUS
momentarily during VBUS pulsing.
