Configuration Word Bits
These configuration bits specify some of the modes of the device, and are programmed by a
device programmer, or by using the In-Circuit Serial Programming (ICSP) feature of the midrange
devices. The device is not able to read the values of these bits, and there placement is automat-
ically taken care of when you select the device in you device programmer. For additional infor-
mation, please refer to the Programming Specification of the Device.
CP1:CP0: Code Protection bits
11 = Code protection off
10 = See device data sheet
01 = See device data sheet
00 = All memory is code protected
DP: Data EEPROM Memory Code Protection bit
1 = Code protection off
0 = Data EEPROM Memory is code protected
BODEN: Brown-out Reset Enable bit
1 = BOR enabled
0 = BOR disabled
PWRTE: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
MCLRE: MCLR Pin Function Select bit
1 = Pin’s function is MCLR
0 = Pin’s function is as a digital I/O. MCLR is internally tied to V
WDTE: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
Note 1: Always ensure that your device programmer has the same device selected as you
Note 2: Microchip recommends that the desired configuration bit states be embedded in to

the application source code. This is easily done in the MPASM assembler by the use
of the CONFIG directive. See Subsection
Some devices may use more or less bits to determine the code protect. Presently
there are also some devices that use only one bit (CP0). For these devices the bit
description is:
1 = Code protection off
0 = Code protection on
This bit is used when a device with ROM program memory also has Data EEPROM
memory.
Enabling Brown-out Reset automatically enables the Power-up Timer (PWRT)
regardless of the value of bit PWRTE. Ensure the Power-up Timer is enabled any-
time Brown-out Reset is enabled.
