For PIC16F193X only.
For PIC16F194X only.
The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
Unemplemented on PIC16LF190X devices. This bit reads as ‘1’.
For PIC16LF190X only.
LVP: Low-Voltage Programming Enable bit
1 = Low-voltage programming enabled
0 = 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’
ULPBOR: Ultra Low-Power BOR Enable bit
1 = Ultra low-power BOR is disabled
0 = Ultra low-power BOR is enabled
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’
