Protection Description
No program lock features enabled.
MOVC instruction executed from external program memory are
disabled from fetching code bytes from internal memory, EA is sampled
and latched on reset, and further parallel programming of the Flash is
disabled.
ISP and software programming with API are still allowed.
Writing EEprom Data from external parallel programmer is disabled but
still allowed from internal code execution.
Same as 2, also verify through parallel programming interface is
disabled.
Writing And Reading EEPROM Data from external parallel programmer
is disabled but still allowed from internal code execution..
Same as 3, also external execution is disabled
