Hi, Many Thanks to your feedback...
If you can confirm hackers can't exploit that window, I believe
the chip could be read protected properly.

The others issues:
- Any undocumented command, i.e. 'T' commands
- JTAG boundary scans
could be protected by the bootloader, as long as bootloader
disables them when CRP enabled.

Reverse disassembly of bootloader is of no use in hacking the chip.
