The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
This bit must be programmed as a ‘1’.
LVP: Low-Voltage Programming Enable bit
1 = Low-voltage programming enabled
0 = HV on MCLR/V
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
0 = Brown-out Reset voltage set to 2.7V
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: Read as ‘1’
Unimplemented: Read as ‘1’
WRT<1:0>: Flash Memory Self-Write Protection bits

DEBUG
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
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
