Indicates that the external PHY is able to accept
data from the USB controller.
TTLO104USB0DIR
Bidirectional differential data pin (D- per USB
specification) for USB0.
AnalogI/O93USB0DM
Bidirectional differential data pin (D+ per USB
specification) for USB0.
AnalogI/O94USB0DP
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).
AnalogI95USB0ID
Asserted by the external PHY to throttle all data
types.
TTLO103USB0NXT
Optionally used in Host mode by an external power
source to indicate an error state by that power
source.
TTLI41
128
USB0PFLT
Asserted by the USB controller to signal the end of
a USB transmit packet or register write operation.
TTLO91USB0STP
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.
