The error recovery state is equivalent to force a detach event. When entering this state, the device de-asserts the

from the CC pins. Then, it transitions to the unattached state.

The STUSB4500L goes into error recovery state when at least one condition listed below is met:

•

•

The detection of a hardware fault is advertised through the GPIO pin when configured in ERROR_RECOVERY

mode.

See Section 7 Electrical characteristics for threshold values.

3.6

Debug accessory mode detection

The STUSB4500L detects a connection to a debug and test system (DTS) as defined in the USB Type-C

standard specification. The debug accessory detection is advertised through the GPIO pin when configured in

DEBUG mode.

connected device. The voltage levels on the CC1 and CC2 pins give the orientation and current capability as

described in the table below. The GPIO pin configured in DEBUG mode is asserted to advertise the DTS

detection and the A_B_SIDE pin indicates the orientation of the connection.
