As a former SFI A320 at AIRBUS TRAINING CENTER TOULOUSE we used to request PF call out at every action on FCU when A/P is ON just to keep PNF/PM in the loop .
We had an exemple:
Southern arrival at LFLL(LYON) if you are clear for approach very early and then set Altitude 3000 if you PULL ALT knob you will descend too early and EGPWS warning will be triggered when reaching 3000ft. If you PUSH (manage ALT)you will have an ALT CSTR and your FCU at 3000 will give a magenta 7000 (or higher)on PFD and the aircraft will follow step by step the vertical path required by procedure (don't forget to check ALT CSTR in FMGC)
