DESCRIPTION
3.3V PHY Supply. Provides power for USB 2.0
Transceiver, UTMI+ Digital, Digital I/O, and
Regulators.
Host Disconnect. In HS Host mode this indicates to
that a downstream device has been disconnected.
Automatically reset to 0b when Low Power Mode is
entered.
Discharge VBUS through a resistor to ground.
0: do not discharge VBUS
1: discharge VBUS
Session End. Indicates that the voltage on Vbus is
below its B-Device Session End threshold.
0: VBUS > V
1: VBUS < V
8-bit bi-directional data bus. Data[7] is the MSB and
Data[0] is the LSB.
PHY ground.
Receive Data Valid. Indicates that the DATA bus has
received valid data. The Receive Data Holding
Register is full and ready to be unloaded. The Link
is expected to register the DATA bus on the next
rising edge of CLKOUT.
Session Valid. Indicates that the voltage on Vbus is
above the indicated threshold.
0: VBUS < V
1: VBUS > V
