i think you're getting yrself confused here.
the pitch limits and the high and lowspeed limits coincide.
the aircraft monitors the limits of yr pitch vs airspeed and from this it calculates comes yr low speed and high speed and also yr load protections.
its not 2 seperate things. they work all together to get these protections. if u are talking about pitch on take off... well... if u ain't thinking tailstrike then........................................................ .......................
