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

bit 13
bit 12
LVP: Low-Voltage Programming Enable bit
1= Low-voltage programming enabled
0= High-voltage on MCLR/VPP must be used for programming
DEBUG: In-Circuit Debugger Mode bit
1= In-Circuit Debugger disabled, RB6/ICSPCLK and RB7/ICSPDAT are general purpose I/O pins
0= In-Circuit Debugger enabled, RB6/ICSPCLK and RB7/ICSPDAT are dedicated to the debugger

WRT<1:0>: Flash Memory Self-Write Protection bits
8 kW Flash memory (PIC16F/LF1946 only):
11= Write protection off
10= 000h to 1FFh write-protected, 200h to 1FFFh may be modified by EECON control
01= 000h to FFFh write-protected, 1000h to 1FFFh may be modified by EECON control
00= 000h to 1FFFh write-protected, no addresses may be modified by EECON control
16 kW Flash memory (PIC16F/LF1947):
11= Write protection off
10= 000h to 1FFh write-protected, 200h to 3FFFh may be modified by EECON control
01= 000h to 1FFFh write-protected, 2000h to 3FFFh may be modified by EECON control
00= 000h to 3FFFh 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.
