The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
Reads as ‘11’ on PIC16LF193X only.
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<1:0>: Voltage Regulator Capacitor Enable bits
00 = V
01 = V
10 = V
11 = No capacitor on V
Unimplemented: Read as ‘1’
