Description

USB0DM

70

I/O

Analog Bidirectional differential data pin (D- per USB

specification) for USB0.

USB0DP

71

I/O

Analog Bidirectional differential data pin (D+ per USB

specification) for USB0.

USB0EPEN

O

TTL

Optionally used in Host mode to control an external

power source to supply power to the USB bus.

USB

USB0ID

66

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

I

TTL

Optionally used in Host mode by an external power

source to indicate an error state by that power

source.

USB0RBIAS

73

O

Analog 9.1-kÎ© resistor (1% precision) used internally for

USB analog circuitry.

USB0VBUS

67

I/O

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.
