Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
P = Programmable bit

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
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
Unimplemented: Read as ‘1’
BORV: Brown-out Reset Voltage Selection bit
1 = Brown-out Reset voltage set to 1.9V (typical)
0 = Brown-out Reset voltage set to 2.5V (typical)
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
PLLEN: PLL Enable bit
1 = 4xPLL enabled
0 = 4xPLL disabled
Unimplemented: Read as ‘1’
Reserved: This location should be programmed to a ‘1’.
Unimplemented: Read as ‘1’
WRT<1:0>: Flash Memory Self-Write Protection bits
11 = Write protection off
10 = 000h to 1FFh write-protected, 200h to 7FFh may be modified by EECON control
01 = 000h to 3FFh write-protected, 400h to 7FFh may be modified by EECON control
00 = 000h to 7FFh write-protected, no addresses may be modified by EECON control
Note 1: The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
