At least on A320. It is like a scratch pad entry. When you get the load sheet and final figures you cannot set the THS or configuration as there is no hydraulics. So you may have to write it on paper or memorize it. Instead you enter it on PERF page and after start set them accordingly. It doesn't go into the system and will create no warning or reminder unlike Flex which enters into the system. It is different on A330/340/350 models.

Vilas, on our A 320 fleet, we do get an Ecam warning:" F/CTL PITCH TRIM/MCDU/CG DISAGREE" if the real pitch trim value and the pitch trim value entered in the MCDU are not the same.
I had once this warning after engine start as I inadvertently inserted 5UP instead of 0.5UP in the MCDU.
I guess this feature is optional as before we had this only on the brand new aircraft and now it's installed in the whole fleet.

Recently our fleet have had a FWC upgrade and now we have an ECAM ( only available in phase 2 + 3) that is triggered by a disagree between real pitch trim value and that of the MCDU PERF TO page. The FLAP setting on the PERF TO page will also trigger a TO CONFIG caution if it disagrees from MCDU and SELECTOR.
Earlier models they are just reminders.

I came across this in some CBT programme.
"The pitch setting is shown on the ECAM F/CTL Page.This can be checked during the Flight Control check when taxiing, if required.
Note: Never use this indication for the takeoff trim adjustment. Prefer the scales besides the trim wheels and on the QRH. Because they refer to the takeoff CG position"
What exactly is meant by this?

The old procedure to set the TO stab was to set so many degrees nose up or down and that was done by checking that on Flt Ctl page. But pilots made mistakes of setting NU when it should have been ND. So this practice was stopped and trim was set by the percentage on trim wheel. Like 30% is 30% there is no up or down so no chance of a mistake.
