Note 1:
LVP: Low-Voltage Programming Enable bit
1 = Low-voltage programming enabled
0 = High-voltage on MCLR must be used for programming
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
LPBOR: Low-Power BOR bit
1 = Low-Power BOR is disabled
0 = Low-Power BOR is enabled
BORV: Brown-out Reset Voltage Selection bit
1 = Brown-out Reset voltage set to 1.9V (typical)
0 = Brown-out Reset voltage set to 2.5V (typical)
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
Unimplemented: Read as ‘1’
VCAPEN: Voltage Regulator Capacitor Enable bits⁽¹⁾
If PIC16LF1526/27 (regulator disabled):
These bits are ignored. All VCAP pin functions are disabled.
If PIC16F1526/27 (regulator enabled):
0 = VCAP functionality is enabled on RF0.
1 = All VCAP pin functions are disabled
Unimplemented: Read as ‘1’
WRT<1:0>: Flash Memory Self-Write Protection bits
8 kW Flash memory (PIC16(L)F1526 only):
11 = Write protection off
10 = 000h to 1FFh write-protected, 200h to 1FFFh may be modified by PMCON control
01 = 000h to FFFh write-protected, 1000h to 1FFFh may be modified by PMCON control
00 = 000h to 1FFFh write-protected, no addresses may be modified by PMCON control
16 kW Flash memory (PIC16(L)F1527 only):
11 = Write protection off
10 = 000h to 1FFh write-protected, 200h to 3FFFh may be modified by PMCON control
01 = 000h to 1FFFh write-protected, 2000h to 3FFFh may be modified by PMCON control
00 = 000h to 3FFFh write-protected, no addresses may be modified by PMCON control
PIC16F1526/27 only.
