A Security Lock Byte located at the last byte of Flash user space (3DFFh)
offers protection of the Flash program memory from access (reads,
writes, or erases) by unprotected code or the C2 interface. The Flash
security mechanism allows the user to lock n 512-byte Flash pages,
starting at page 0 (addresses 0x0000 to 0x01FF), where n is the 1's
complement number represented by the Security Lock Byte. Note that the
page containing the Flash Security Lock Byte is unlocked when no other
Flash pages are locked (all bits of the Lock Byte are '1') and locked
when any other Flash pages are locked (any bit of the Lock Byte is '0').

The address range from 3C00h to 3DFFh are locked only
if any other pages are locked.

При установке защиты верификация последнего блока не проходит!
