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'.
LVP: Low-Voltage Programming Enable bit
1 = Low-voltage programming enabled
0 = High-voltage on MCLR/V
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
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 2.5V
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’
VCAPEN>: Voltage Regulator Capacitor Enable bits
0 = V
1 = No capacitor on V
Unimplemented: Read as ‘1’
