DESCRIPTION
Enables Link to turn on 60MHz CLKOUT in Serial
Mode or Carkit Mode.
0b: Disable clock in serial or Carkit Mode.
1b: Enable clock in serial or Carkit Mode.
Only applicable in Host mode. Enables the
transceiver to automatically transmit resume
signaling. This function is detailed in
Inverts the EXTVBUS signal. This function is detailed
in
Note:
Disables and’ing the internal VBUS comparator with
the EXTVBUS signal when asserted. This function is
detailed in
Note:
Used to disable the integrated STP pull-up resistor
used for interface protection. This function is detailed
in
DESCRIPTION
Connects a 100kΩ pull-up resistor from the ID pin to
VDD33
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
1b: Pull-down resistor connected
Enables the 15k Ohm pull-down resistor on DM.
0b: Pull-down resistor not connected
1b: Pull-down resistor connected
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 VDD33 to charge VBUS above the
SessValid threshold.
0b: disconnect resistor from VBUS to VDD33
1b: connect resistor from VBUS to VDD33
Enables external 5 volt supply to drive 5 volts on
VBUS. This signal is or’ed with DrvVbusExternal.
0b: Do not drive Vbus, CPEN driven low.
1b: Drive Vbus, CPEN driven high.
