It's been a while since I touched the 'bus, but I remember a few things:
Bank angle is basically limited to 67deg, with the flight control system returning it to 33deg when you release the stick. In normal control mode, that's always the same..
Now, with autopilot on, the system will recognise an EF situation and fly the procedures with 15deg bank angle until "green dot" speed is reached, green dot being a function of VS. As long as the autopilot is on, sideslip is also controlled, but I don't remember what the limit is...
With autopilot off, no limit is made on sideslip, except of course the traditional rudder throw limiter as a function of speed...
