Once you are flagged you must either wait 90 days or deposit more than $25k..   Brokers are able to reset the flag once per 180 days 5 days after the flag was placed.   If you get re-flagged after the reset, you must wait out the 90 day sentence.

Please read the post, I know how PDT works. Also, the 180 days you're referring to is determined by the broker and cleaning house. For example, Tradier will reset the flag once ever 90 days.
