Bidirectional differential data pin (D- per USB
specification) for USB0.
Bidirectional differential data pin (D+ per USB
specification) for USB0.
Optionally used in Host mode to control an external
power source to supply power to the USB bus.

TTL
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).
Optionally used in Host mode by an external power
source to indicate an error state by that power
source.

9.1-kΩ resistor (1% precision) used internally for
USB analog circuitry.
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.
Power source for the Hibernation module. It is
normally connected to the positive terminal of a
battery and serves as the battery
backup/Hibernation module power-source supply.
Positive supply for I/O and some logic.
