Enabling Brown-out Reset does not automatically enable Power-up Timer.
The entire data EEPROM will be erased when the code protection is disabled during an erase.
The entire program memory will be erased when the code protection is disabled during an erase.
Unimplemented: Read as ‘1’.
FCMEN: Fail-Safe Clock Monitor Enable bit
1 = Fail-Safe Clock Monitor is enabled
0 = Fail-Safe Clock Monitor is disabled
IESO: Internal External Switchover bit
