15.7 Security
MC95FG308 provides Lock bits which can be left unprogrammed (“0”) or can be programmed (“1”) to obtain the
additional features listed in Table 15.6. The Lock bits can be erased to “0” with only the bulk erase command and a
value of more than 0x80 at FETCR.

Security policy using lock-bits
•
LOCKF: Lock bit of Flash memory
•
LOCKE: Lock bit of data EEPROM
•
R: Read
•
W: Write
•
PE: Page erase
•
BE: Bulk Erase
•
O: Operation is possible.
•
X: Operation is impossible.
•
◇
: When LOCKE is programmed, each operation can be done after data EEPROM is erased with the bulk
erase command.
