Breakpoints are working, but sometimes there is a GUI bug which needs to be fixed.
This bug is maybe caused by multithreading.
Added an binding from the GUI to the backend to allow the change of tris a and b via checkboxes.
There is a bug, which only allows the user to set bits of b when a is already set.
Fixed the bug in the tris a and b registers. Now they are booth separately editable.
