Description
USB0DM
45
I/O
Analog Bidirectional differential data pin (D- per USB
specification) for USB0.
USB0DP
46
I/O
Analog Bidirectional differential data pin (D+ per USB
specification) for USB0.
USB0EPEN
14
O
TTL
Optionally used in Host mode to control an external
power source to supply power to the USB bus.
USB
USB0ID
41
I
Analog 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).
USB0PFLT
15
I
TTL
Optionally used in Host mode by an external power
source to indicate an error state by that power
source.
USB0RBIAS
48
O
Analog 9.1-kΩ resistor (1% precision) used internally for
USB analog circuitry.
USB0VBUS
42
I
Analog 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.
a. The TTL designation indicates the pin has TTL-compatible voltage levels.
