Hello,

Anyone knows how this is possible ?

I do a cross reference (F11) on a output (cmd) bit and in the cross reference I can find that signal only in read only and cannot see where it is written ?

Do you have Knowhow protection in the project? That will break cross referencing and can render it useless depending on how much of the project is knowhow protected.
