bit 6

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘1’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

P = Programmable bit

bit 13

LVP: Low-Voltage Programming Enable bit(1)

1 = Low-voltage programming enabled

0 = High-voltage on MCLR must be used for programming

bit 12

DEBUG: In-Circuit Debugger mode bit(2)

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

bit 11

Unimplemented: Read as ‘1’

bit 10

BORV: Brown-out Reset Voltage Selection bit

1 = Brown-out Reset voltage set to 1.9V (typical)

0 = Brown-out Reset voltage set to 2.7V (typical)

bit 9

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

bit 8

PLLEN: PLL Enable bit

1 = 4xPLL enabled

0 = 4xPLL disabled

bit 7-5

Unimplemented: Read as ‘1’

bit 4

Reserved: This location should be programmed to a ‘1’.

bit 3-2

Unimplemented: Read as ‘1’

bit 1-0

WRT<1:0>: Flash Memory Self-Write Protection bits

11 = Write protection off

10 = 000h to 1FFh write-protected, 200h to FFFh may be modified by EECON control

01 = 000h to 7FFh write-protected, 800h to FFFh may be modified by EECON control

00 = 000h to FFFh 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.

The DEBUG bit in Configuration Word is managed automatically by device development tools including debuggers and

programmers. For normal device operation, this bit should be maintained as a ‘1’.
