12.1 Configuration Bits
The configuration bits can be programmed (read as '0'), or left unprogrammed (read as '1'), to select various device configurations. The erased, or unprogrammed value of the configuration word is 3FFFh. These bits are mapped in program memory location 2007h.
It is important to note that address 2007h is beyond the user program memory space, which can be accessed only during programming.
