PS28, Line 104: use special commands for modifying it
> `specialised command used to modifying it` ?

Hmmm, this sounds very confusing... The current `use special commands for modifying it` sounds like it's telling the user how to proceed, but it doesn't make sense.

Can't find if writing the SECURITY register is implemented in a future patch. How about using `Cannot write SECURITY: special commands not yet implemented` instead?
