Legend:
R = Readable bit
‘0’ = Bit is cleared
P = Programmable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘1’
-n = Value when blank or after Bulk Erase

bit 1-0
LVP: Low-Voltage Programming Enable bit⁽¹⁾
1 = Low-voltage programming enabled
0 = High-voltage on MCLR must be used for programming
DEBUG: In-Circuit Debugger Mode bit⁽³⁾
1 = In-Circuit Debugger disabled, ICSPCLK and ICSPDAT are general purpose I/O pins
0 = In-Circuit Debugger enabled, ICSPCLK and ICSPDAT are dedicated to the debugger
LPBOR: Low-Power BOR Enable bit
1 = Low-Power Brown-out Reset is disabled
0 = Low-Power Brown-out Reset is enabled
BORV: Brown-out Reset Voltage Selection bit⁽²⁾
1 = Brown-out Reset voltage (Vbor), low trip point selected.
0 = Brown-out Reset voltage (Vbor), high trip point selected.
STVREN: Stack Overflow/Underflow Reset Enable bit
1 = Stack Overflow or Underflow will cause a Reset
0 = Stack Overflow or Underflow will not cause a Reset
Unimplemented: Read as ‘1’
WRT<1:0>: Flash Memory Self-Write Protection bits
2 kW Flash memory:
11 = Write protection off
10 = 000h to 1FFh write-protected, 200h to 7FFh may be modified
01 = 000h to 3FFh write-protected, 400h to 7FFh may be modified
00 = 000h to 7FFh write-protected, no addresses may be modified
Note 1:

3:
The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
See Vbor parameter for specific trip point voltages.
The DEBUG bit in Configuration Words is managed automatically by device development tools including
debuggers and programmers. For normal device operation, this bit should be maintained as a '1'.
