PROTECTION DESCRIPTION
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 jumped and latched on Reset, and further programming of the EPROM Is disabled.
Same as 2, also verify is disabled.
Same as 3, external execution is disabled. Internal data RAM is not accessible.
