PIC16F8X
8.1 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.
Address 2007h is beyond the user program memory
space and it belongs to the special test/configuration
memory space (2000h - 3FFFh). This space can only
be accessed during programming.
To find out how to program the PIC16C84, refer to
PIC16C84 EEPROM Memory Programming Specifica-
tion (DS30189).
