Narrative:

On takeoff captain applied power to the flex/mct detent. I recall hearing 2 clicks. Captain read FMA's as man flex; speed reference system. Sometime before 80 kts I noticed the auto throttle FMA was man thr outlined in amber. As I was looking at that we received a master caution and [I'm] not positive what was on ECAM but I believe 'auto thrust takeoff/go around'. I was confused at first because I knew we had set a flex temp and after clearing the runway we confirmed a flex temp was set. Due to the distraction of the FMA change and master caution we passed 80 kts without a callout from me. The captain aborted the takeoff and max auto brakes engaged. We cleared the runway; talked to flight attendants and passengers; determined the need for maintenance inspection and returned to gate. Maintenance was unable to determine the cause of ECAM as a flex temp was set.
