Thank you JPortici for your answer.
I think the following table resumes the table 4-2 in a much more terse and understandable way. Could you check if the table looks correct ?
Target is the memory segment which we try to read/write/erase.
The table states the highest security level that makes the operation possible.
E.g. is the highest security level is 2 (standard), then the operation is possible only
with None and Standard, but not with High.
Anyone can feel free to comment, correct, ecc...
GS security level
CODE EXECUTES FROM
BS 3 1
GS 2 3
Write and Erase are never allowed if the corresponding write protection is ON.
