It's even easier: according to the manual, you can simply turn off
the protection and then scribble over things, see .

Yes, they look very very good. Their main problem is that they seem
brickable. This could be solved by booting from a serial flash
(STR750 family, ), but that would add yet another component,
which isn't desirable.
 "STR7 family Flash programming"
 "STR750 ARM7TDMI-S-based microcontroller family Reference Manual"
sections 1.4 and 1.4.2.
Oh, and I forgot the most important requirement: fully documented
without silly restrictions :)
