USBDCD_STATUS field descriptions
Description
This read-only field is reserved and always has the value zero.
Active Status Indicator
Indicates whether the sequence is running.
0b0 The sequence is not running.
0b1 The sequence is running.
Timeout Flag
Indicates whether the detection sequence has passed the timeout threshhold.
0b0 The detection sequence has not been running for over 1 s.
0b1 It has been over 1 s since the data pin contact was detected and debounced.{
Error Flag
Indicates whether there is an error in the detection sequence.
0b0 No sequence errors.
0b1 Error in the detection sequence. See the SEQ_STAT field to determine the phase in which the error
occurred.
Charger Detection Sequence Status
Indicates the status of the charger detection sequence.
0b00

No results to report.
Attached to a standard host. Must comply with USB Spec 2.0 by drawing only 2.5mA (max) until
connected.
Attached to a charging port. The exact meaning depends on bit 18: 0: Attached to either a
charging host or a dedicated charger (The charger type detection has not completed.) 1: Attached
to a charging host (The charger type detection has completed.)
Attached to a dedicated charger.
