USB3320
7.1.1.6 Interface Control
Address = 07-09h (read), 07h (write), 08h (set), 09h (clear)
7.1.1.7 OTG Control
Address = 0A-0Ch (read), 0Ah (write), 0Bh (set), 0Ch (clear)
SuspendM 6 rd/w/s/c 1b Active low PHY suspend. When cleared the
transceiver will enter Low Power Mode as detailed in
Section 6.3. Automatically set when exiting Low Power
Mode.
Reserved 7 rd 0b Read only, 0.
Field Name Bit Access Default Description
6-pin FsLsSerialMode 0 rd/w/s/c 0b When asserted the ULPI interface is redefined to the
6-pin Serial Mode. The transceiver will automatically
clear this bit when exiting serial mode.
3-pin FsLsSerialMode 1 rd/w/s/c 0b When asserted the ULPI interface is redefined to the
3-pin Serial Mode. The transceiver will automatically
clear this bit when exiting serial mode.
CarkitMode 2 rd/w/s/c 0b When asserted the ULPI interface is redefined to the
Carkit interface. The transceiver will automatically
clear this bit when exiting Carkit Mode.
ClockSuspendM 3 rd/w/s/c 0b 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.
AutoResume 4 rd/w/s/c 0b Only applicable in Host mode. Enables the transceiver
to automatically transmit resume signaling. This
function is detailed in Section 6.2.4.4.
IndicatorComplement 5 rd/w/s/c 0b Inverts the EXTVBUS signal. This function is detailed
in Section 5.6.2.
Note: The EXTVBUS signal is always high on the
USB3320.
IndicatorPassThru 6 rd/w/s/c 0b Disables and’ing the internal VBUS comparator with
the EXTVBUS signal when asserted. This function is
detailed in Section 5.6.2.
Note: The EXTVBUS signal is always high on the
USB3320.
InterfaceProtectDisable 7 rd/w/s/c 0b Used to disable the integrated STP pull-up resistor
used for interface protection. This function is detailed
in Section 6.3.3.
Field Name Bit Access Default Description
IdPullup 0 rd/w/s/c 0b Connects a 100kΩ pull-up resistor from the ID pin to
VDD33
0b: Disables the pull-up resistor
1b: Enables the pull-up resistor
DpPulldown 1 rd/w/s/c 1b Enables the 15k Ohm pull-down resistor on DP.
0b: Pull-down resistor not connected
1b: Pull-down resistor connected
DmPulldown 2 rd/w/s/c 1b Enables the 15k Ohm pull-down resistor on DM.
0b: Pull-down resistor not connected
1b: Pull-down resistor connected
