POWER INTERRUPT STATUS REGISTER (PWR_INT_STS)

Address:

080Ah

Size:

8 bits

Bits

Description

Type

Default

VBUS_MATCH_VLD

Asserts after the VBUS debouncer is first enabled, via VBUS Comparator

Control, and the first match becomes valid in VBUS Match Register (VBUS_-

MATCH).

R/WC

VCONN Discharge Error (VCONN_DISCH_ERR)

When set this bit indicates that a VCONN discharge error has been detected.

This bit is only available in standalone DFP mode and is otherwise reserved.

A discharge error is tracked when VCONN Discharge Control is set to 00b

or 01b. A discharge error is asserted when VCONN fails to fall below VCONN

Discharge Threshold (VCONN_DIS_THR) after a time greater than VCONN

Discharge Time (VCONN_DIS_TIME) elapses.

R/WC

CC2 Back-Drive Error

When set, indicates that back-drive has been detected on the CC2 pin.

Note:

The source of this input is a level and persists until the error condi-

tion stops.

R/WC

VBUS Discharge Error

When set, indicates that the an interval greater than defined in the VBUS Off

Note:

The source of this input is a pulse and does not persist after being

cleared.

R/WC

VCONN2 FET Power

The integrated VCONN2 FET is enabled and providing power.

This bit only has usefulness for standalone operation or where VCONN is

explicitly enabled by the host.

Note:

The source of this input is a level and persists until the VCONN is

no longer present.

R/WC

VCONN1 FET Power

The integrated VCONN1 FET is enabled and providing power.

This bit only has usefulness for standalone operation or where VCONN is

explicitly enabled by the host.

Note:

The source of this input is a level and persists until the VCONN is

no longer present.

R/WC

CC1 Back-Drive Error

When set indicates that back-drive has been detected on the CC1 pin.

Note:

The source of this input is a level and persists until the error condi-

tion stops.

R/WC

VCONN Over-Current Error

Indicates an over-current has been detected on the integrated VCONN FET.

Note:

The source of this input is a level and persists until the error condi-

tion stops.

R/WC
