Config space and password protection

[Acexbe]

The product page states that code on the ezsbc1 can be password protected.
I did not found how to in the manual.

The 4k config space can be filled with data that can be used by both code banks.
What is the remaining space in the config space (besides the regular entry's like 'Auto and Startuptime).

Still exploring this little cute thing...

Ok,

I guess the smallest block in flash memory you can write is 4k.
So bisedes the config parameters, the rest is free and reachable for both program banks.
