2 except read operation isn’t available. The fourth level
of security is the most secure level. It doesn’t allow
read/program of internal memory or boot from external
memory. Please note that for unused combinations of
the security lock bits, the chip will default to Level 4
status. For details on how to program the security lock
bits refer to the External Host Mode and In-Application
Programming Section.

Security Type
No Security Features are Enabled.
MOVC instructions executed from
external program memory are dis-
abled from fetching code bytes from
internal memory, EA# is sampled and
latched on Reset, and further pro-
gramming of the flash is disabled.
Level 2 plus Verify disabled, both
blocks locked.
Level 2 plus Verify disabled. Code in
Block 1 may program Block 0 and vice
versa.
Level 2 plus Verify disabled. Code in
Block 1 may program Block 0.
Same as Level 3 Hard Lock/Hard
Lock, but MCU will start code execu-
tion from the internal memory regard-
less of EA#.
