bit 13 bit 8
U-1U-1U-1U-1U-1U-1R/P-1R/P-1
—WRT<1:0>
bit 7 bit 0
Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘1’
‘0’ = Bit is cleared ‘1’ = Bit is set -n = Value when blank or after Bulk Erase
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
(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
bit 11
LPBOR
: Low-Power BOR Enable bit
1 = Low-Power Brown-out Reset is disabled
0 = Low-Power Brown-out Reset is enabled
bit 10 BORV: Brown-Out Reset Voltage Selection bit
(2)
1 = Brown-out Reset voltage (VBOR), low trip point selected
0 = Brown-out Reset voltage (V
BOR), high trip point selected
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 8-2 Unimplemented: Read as ‘1
bit 1-0 WRT<1:0>: Flash Memory Self-Write Protection bits
4 kW Flash memory (
PIC16(L)F1508 only)
11 = Write protection off
10 = 000h to 1FFh write protected, 200h to FFFh may be modified
01 = 000h to 7FFh write protected, 800h to FFFh may be modified
00 = 000h to FFFh write protected, no addresses may be modified
8 kW Flash memory (PIC16(L)F1509 only)
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
Note 1: The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
2: See V
BOR parameter for specific trip point voltages.
3: 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’.
