the state of D+; LINESTATE[1] reflects state of D-.
00: SE0
01: J State
10: K State
11: SE1
UTMI_OPMODE[1:0]
Out
Selects Operating mode
00: Normal operation
01: Non-driving
10: Bit stuffing and NRZI encoding disabled
11: Reserved
UTMI_XDATAIN[7:0]
In
Received data
UTMI_XDATAOUT[7:0]
Out
Data to be transmitted
UTMI_TXVALID
Out
Transmit data valid. Indicates that valid data has been transmitted.
UTMI_TXREADY
In
Transmit data ready. Indicates that the transmitter requires data.
UTMI_RXVALID
In
Receive data valid. Indicates that valid data has been received.
UTMI_RXACTIVE
In
Indicates that a valid packet is being received.
UTMI_RXERROR
In
Indicates that the received packet is about to be aborted due to an error.
UTMI_XCVRSEL[1:0]
Out
Transceiver select
00: HS transceiver
01: FS transceiver
10: LS transceiver
11: FS transceiver, LS packet
UTMI_TERMSEL
Out
Termination select. When 0, high speed termination is enabled; when 1, full
speed termination is enabled.
May be used to switch the pull-up resistor on D+
UTMI_VBUSVALID
In
Compares VBus to selected VBus valid threshold (required to be between
4.4 V and 4.75 V)
1: Above the VBus valid threshold
0: Below the VBus valid threshold
UTMI_AVALID
In
Compares VBus to session valid threshold for a B device (required to be
between 0.8 V and 2 V)
1: Above the session valid threshold
0: Below the session valid threshold
UTMI_SESSEND
In
Compares VBus to session end threshold (required to be between 0.2 V
and 0.8 V)
0: Above the session end threshold
1: Below the session end threshold
UTMI_SESSEND
In
Compares VBus to session end threshold (required to be between 0.2 V
and 0.8 V)
0: Above the session end threshold
1: Below the session end threshold
UTMI_DRVVBUS
Out
Enables VBus power (used when the USB controller operates as an A
device)
UTMI_CHRGVBUS
Out
Charges VBus (used during session request when the USB controller
operates as a B device)
