Enabling Brown-out Reset does not automatically enable Power-up Timer.
The entire data EEPROM will be erased when the code protection is turned off during an erase.
The entire program memory will be erased when the code protection is turned off.
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
1 = Internal/External Switchover mode is enabled
0 = Internal/External Switchover mode is disabled
CLKOUTEN: Clock Out Enable bit
1 = CLKOUT function is disabled. I/O or oscillator function on RA6/CLKOUT
0 = CLKOUT function is enabled on RA6/CLKOUT
