No Program Lock features enabled (Code verify will still be encrypted by the
Encryption Array if programmed )
MOVC instructions executed from external program memory are disabled from
fetching code bytes from internal memory EA is sampled and latched on
Reset and further programming of the EPROM is disabled
Same as 2 also verify is disabled
Same as 3 also external execution is disabled
