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
PLLEN: PLL Enable bit
1 = PLL is enabled
0 = PLL is disabled
PLLMULT: PLL Multiplier Selection bit
1 = 3x PLL Output Frequency is selected
0 = 4x PLL Output Frequency is selected
USBLSCLK: USB Low-Speed Clock Selection bit
1 = USB Clock divide-by 8 (48 MHz system input clock expected)
0 = USB Clock divide-by 4 (24 MHz system input clock expected)
CPUDIV<1:0>: CPU System Clock Selection bits
11 = CPU system clock divided by 6
10 = CPU system clock divided by 3
01 = CPU system clock divided by 2
00 = No CPU system clock divide
Unimplemented: Read as ‘1’
WRT<1:0>: Flash Memory Self-Write Protection bits
8 kW Flash memory:
11 = Write protection off
10 = 000h to 01FFh write-protected, 0200h to 1FFFh may be modified
01 = 000h to 0FFFh write-protected, 1000h to 1FFFh may be modified
00 = 000h to 1FFFh write-protected, no addresses may be modified

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'.
