PIC16C62X
9.1 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.
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.

CP<1:0>: Code protection bit pairs (2)
Code protection for 2K program memory
11 = Program memory code protection off
10 = 0400h-07FFh code protected
01 = 0200h-07FFh code protected
00 = 0000h-07FFh code protected
Code protection for 1K program memory
11 = Program memory code protection off
10 = Program memory code protection off
01 = 0200h-03FFh code protected
00 = 0000h-03FFh code protected
bit 7
bit 6
bit 3
bit 2
bit 1-0
Code protection for 0.5K program memory
11 = Program memory code protection off
10 = Program memory code protection off
01 = Program memory code protection off
00 = 0000h-01FFh code protected
Unimplemented: Read as ‘0’
BODEN: Brown-out Reset Enable bit (1)
1 = BOR enabled
0 = BOR disabled
PWRTE: Power-up Timer Enable bit (1, 3)
1 = PWRT disabled
0 = PWRT enabled
WDTE: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
FOSC1:FOSC0: Oscillator Selection bits
11 = RC oscillator
10 = HS oscillator
01 = XT oscillator
00 = LP oscillator
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 Detect Reset is
enabled.
2: All of the CP<1:0> pairs have to be given the same value to enable the code protection scheme
listed.
3: Unprogrammed parts default the Power-up Timer disabled.
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
1 = bit is set
U = Unimplemented bit, read as ‘0’
0 = bit is cleared
x = bit is unknown
