BQ28Z610-R1: BQ28Z610-R1 communications issue

Part Number: BQ28Z610-R1
Other Parts Discussed in Thread: BQ28Z610


I have a query need your help.

The bq28z610-r1 communication port is given a pull-up voltage.

When there is no communication with the system, the chip actively sends the waveform signal in the below figure. The time interval of the signal is 1S-14S-1S-14S.

Why does this signal appear? Can it be eliminated?

Waiting for your reply.
