Talked about that creed (9)

I believe the answer is:

chattered

'talked' is the definition.
(chattering is a kind of talking)

'about that creed' is the wordplay.
'about' is an anagram indicator.
'that'+'creed'='thatcreed'
'thatcreed' is an anagram of 'CHATTERED'.

(Another definition for chattered that I've seen is " Talked quickly about trivia - like magpie?".)

I've seen this clue in The Mirror.
