No program lock. Encrypted verify if encryption table was
programmed.
Prevent MOVC instructions in external memory from reading
program bytes in internal memory.
EA
is sampled and latched on
reset. Allow no further programming of EPROM.
Level 2 plus no verify operation. Also, prevent MOVX instructions in
external memory from reading SRAM (MOVX) in internal memory.
Level 3 plus no external execution.
