USB data 6.TTLI/OPP5 (14)B12USB0D6
USB data 7.TTLI/OPP4 (14)D8USB0D7
Indicates that the external PHY is able to accept
data from the USB controller.
TTLOPP3 (14)C12USB0DIR
Bidirectional differential data pin (D- per USB
specification) for USB0.
AnalogI/OPL7B18USB0DM
Bidirectional differential data pin (D+ per USB
specification) for USB0.
AnalogI/OPL6C18USB0DP
Optionally used in Host mode to control an external
power source to supply power to the USB bus.

USB0EPEN
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).
AnalogIPB0A16USB0ID
Asserted by the external PHY to throttle all data
types.
TTLOPP2 (14)B13USB0NXT
Optionally used in Host mode by an external power
source to indicate an error state by that power
source.

USB0PFLT
Asserted by the USB controller to signal the end of
a USB transmit packet or register write operation.
TTLOPB2 (14)A17USB0STP
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.
AnalogI/OPB1B16USB0VBUS
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.
