PIC16CE62X
The user will note that address 2007h is beyond
the user program memory space. In fact, it belongs
to the special test/configuration memory space
(2000h – 3FFFh), which can be accessed only during
programming.
10.1
Configuration Bits
The configuration bits can be programmed (read as '0')
or left unprogrammed (read as '1') to select various
device configurations. These bits are mapped in
program memory location 2007h.

Note 1: Enabling Brown-out Reset automatically enables Power-up Timer (PWRT) regardless of the value of bit PWRTE. Ensure
the Power-up Timer is enabled anytime Brown-out Reset is enabled.
2: All of the CP1:CP0 pairs have to be given the same value to enable the code protection scheme listed.
