There are several laws in which the aircraft may be operated.
Pitch : Normal law, alternate law with reduced protections, alternate law without protections and direct law.
Roll : Normal law, roll direct law with yaw alternate law and roll direct law with yaw mechanical control

Normal law (standard) provides following protections and functions:
Pitch : -AOA-Protection
-High speed protection
-Load factor protection
-Pitch Attitude protection
functions : -Automatic pitch trim
-Unusual attitude protection.

Roll: -Bank angle protection
functions : -Turn coordination
-Yaw damping
-Side slip target for one engine out
-Unusual attitude protection

Stick deflection in normal law demands:

Ground mode : Direct Surface deflection demand
Flight mode : G-load demand (1G = level flight)
(below 50 feet changeover to)
Flare mode : Pitch attitude demand
(after 5 sec on GND AND pitch <2.5° changeover to)
Ground mode : Direct surface deflection

At the end: Pull stick and the houses get smaller, push stick and they get bigger again.
