Configuration Bits
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.
The entire program memory will be erased when the code protection is turned off.
When MCLR is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.
Unimplemented: Read as ‘1’
DEBUG: In-Circuit Debugger Mode bit
1 = In-Circuit Debugger disabled, RB6/ICSPCLK and RB7/ICSPDAT are general purpose I/O pins
0 = In-Circuit Debugger enabled, RB6/ICSPCLK and RB7/ICSPDAT are dedicated to the debugger
LVP: Low Voltage Programming Enable bit
1 =
0 =
FCMEN: Fail-Safe Clock Monitor Enabled bit
1 = Fail-Safe Clock Monitor is enabled
0 = Fail-Safe Clock Monitor is disabled
