Vilas please correct me if I'm wrong but from memory, with the Auto Thrust active and AP ON the aircraft will automatically pitch up until the flaps are fully retracted to prevent an overspeed in climb or will spool down if Auto Thrust is in speed mode to avoid going above Vmax until the flaps are fully retracted.
Airbus training DVD showed that during GA FMGS will restrict the speed to Vmax, Vfe, Vle, Vmo by pitch up even with ATHR left in TOGA. But ALT* overrules that. I have confirmed this in the sim. I think with ATHR in CLB it should protect but some excursion occurs. The following SAFETY FIRST discusses the situation after take off.
