9.1
The configuration bits can be programmed (read as '0'),
or left unprogrammed (read as '1') to select various
device configurations, as shown in Register 9-1. These
bits are mapped in program memory location 2007h.

2: The entire data EEPROM will be erased when the code protection is turned off.
3: The entire program memory will be erased, including OSCCAL value, when the code protection is
4: Enabling Brown-out Detect does not automatically enable Power-up Timer.
5: When MCLR is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.
