DATASHEET
Changes the ULPI interface to a 6-pin Serial Mode. The PHY will
automatically clear this bit when exiting serial mode.
Changes the ULPI interface to a 3-pin Serial Mode. The PHY will
automatically clear this bit when exiting serial mode.
Driven low.
Enables Link to turn on 60MHz CLKOUT in serial mode.
0b: Disable clock in serial mode.
1b: Enable clock in serial mode.
Only applicable in Host mode. Enables the PHY to automatically
transmit resume signaling. This function is detailed in
Section
Inverts the EXTVBUS signal. This function is detailed in
Section
Disables anding the internal VBUS comparator with the
EXTVBUS input when asserted. This function is detailed in
Section
Used to disable the integrated STP pull-up resistor used for
interface protection. This function is detailed in
Connects a pull-up resistor from the ID pin to VDD3.3
0b: Disables the pull-up resistor
1b: Enables the pull-up resistor
Enables the 15k Ohm pull-down resistor on DP.
0b: Pull-down resistor not connected to DP
1b: Pull-down resistor connected to DP
Enables the 15k Ohm pull-down resistor on DM.
0b: Pull-down resistor not connected to DM
1b: Pull-down resistor connected to DM
This bit is only used during SRP. Connects a resistor from VBUS
to ground to discharge VBUS.
0b: disconnect resistor from VBUS to ground
1b: connect resistor from VBUS to ground
This bit is only used during SRP. Connects a resistor from VBUS
to VDD3.3 to charge VBUS above the SessValid threshold.
0b: disconnect resistor from VBUS to VDD3.3
1b: connect resistor from VBUS to VDD3.3
