DEBUG_ACC_CONNECTED |
RU |
0 |
0b: No Debug Accessory connected (default)
1b: Debug Accessory connected
Reflects the state of the DebugAccessoryConnected# output if supported. Even though the TUSB422 doesn’t have a debug accessory pin, TUSB422will set this flag to 1 if a debug accessory is detected. |
6 |
TCPC_INIT_STATUS |
RU |
0 |
0b: The TUSB422 has completed initialization and all registers are valid.
1b: The TUSB422 is still performing internal initialization and the only registers that will return the correct values are 00h..0Fh.
The TUSB422 will never set this flag so software needs to be aware at power-up one reason for INT_N assertion is TUSB422 has completed its initialization. |

SOURCING_HIGH_VOLTAGE |
RU |
0 |
0b: vSafe5V
1b: High Voltage
This does not control the path, just provides a monitor of the status. Assert as long as supplying voltage greater than vSafe5V. |
4 |
SOURCING_VBUS |
RU |
0 |
0b: Sourcing VBUS is disabled
1b: Sourcing VBUS is enabled
This does not control the path, just provides a monitor of the status. |
3 |
VBUS_PRES_DETECT_ENABLED |
RU |
0 |
0b: VBUS Present Detection Disabled (Default)
1b: VBUS Present Detection Enabled
Indicates if the TUSB422 is monitoring for VBUS Present or if the circuit has been powered off |
2 |
VBUS_PRESENT |
RU |
0 |
0b: VBUS Disconnected
1b: VBUS Connected
The TUSB422 shall report VBUS present when TUSB422 detects VBUS rises above 4 V. The TUSB422 shall report VBUS is not present when TUSB422 detects VBUS falls below 3.5 V. The TUSB422 may report VBUS is not present if VBUS is between 3.5 V and 4 V. When this field transitions from 1 to 0, VBUS Sink Disconnect Threshold field is all zeros, and Auto Discharge is enabled, the TUSB422 will discharge to vSafe0V. VBUS present status may be invalid immediately after enabling detection. Software needs to delay 1 polling period (~1ms) after enabling detection before reading VBUS_PRESENT status. |

VCONN_PRESENT |
RU |
0 |
0b: VCONN is not present
1b: This bit is asserted when VCONN present CC1 or CC2. Threshold is fixed at 2.4 V |
0 |
SINKING_VBUS |
RU |
0 |
0b: Sink is Disconnected
1b: TUSB422 is sinking VBUS to the system load |
