0001 0001b

WakeI2C

(no action is taken other than to wake the I2C interface)

0010 0010b

DisableVbusDetect. Disable Vbus present detection:

PWRSTAT.VBUS_VAL. The FUSB307B will ignore this

command and assert the FAULTSTAT.I2C_ERR if it has

sourcing or sinking power over Vbus enabled

0011 0011b

EnableVbusDetect. Enable Vbus present detection

0100 0100b

DisableSinkVbus. Disable sinking power over Vbus.

This COMMAND does not disable PWRSTAT.VBUS_VAL

detection

0101 0101b

SinkVbus. Enable sinking power over Vbus and enable Vbus

present detection. The FUSB307B will ignore this command

and assert the FAULTSTAT.I2C_ERR if it has sourcing power

over Vbus enabled

0110 0110b

DisableSourceVbus. Disable sourcing power over Vbus. This

COMMAND does not disable PWRSTAT.VBUS_VAL

detection

0111 0111b

SourceVbusDefaultVoltage. Enable sourcing vSafe5V over

Vbus and enable Vbus present detection. Source shall

transition to vSafe5V if at a high voltage. The FUSB307B will

ignore this command and assert the FAULTSTAT.I2C_ERR if

it has sinking power over Vbus enabled

1000 1000b

SourceVbusHighVoltage. Execute sourcing high voltage over

Vbus.

FUSB307B will ignore this command and assert the

FAULTSTAT.I2C_ERR

1001 1001b

LOOK4CON. Start DRP Toggling if ROLECTRL.DRP = 1b.

If ROLECTRL.CC1/CC2 = 01b start with Rp,

if ROLECTRL.CC1/CC2 =10b start with Rd.

If ROLE_CONTROL.CC1/CC2 are not either 01b/01b or

10b/10b, then do not start toggling.

The TCPM shall issue .

COMMAND.LOK4CON to enable the device to restart

Connection Detection in cases where the ROLECTRL

contents will not change. An example of this is when a

potential connection as a Source occurred but was further

debounced by the TCPM to find the Sink disconnected. In

this case a Source Only or DRP should go back to its

Unattached.Src state. This would result in ROLECTRL

staying the same

1010 1010b

RxOneMore. Configure the receiver to automatically clear the

RXDETECT register after sending the next GoodCRC.

This is used to shutdown reception of packets at a known

point regardless of packet separation or the depth of the

receive FIFO in the device
