bit 7 bit 0

Legend:

R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘1’

‘0’ = Bit is cleared ‘1’ = Bit is set -n = Value when blank or after Bulk Erase

bit 13 LVP: Low-Voltage Programming Enable bit

1 = Low-voltage programming enabled

0 = High-voltage on MCLR

must be used for programming

bit 12 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

bit 11 LPBOR: Low-Power BOR

1 = Low-Power BOR is disabled

0 = Low-Power BOR is enabled

bit 10 BORV: Brown-out Reset Voltage Selection bit

1 = Brown-out Reset voltage (Vbor), low trip point selected.

0 = Brown-out Reset voltage (Vbor), high trip point selected.

bit 9 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

bit 8-5 Unimplemented: Read as ‘1’

bit 4 VCAPEN

: Voltage Regulator Capacitor Enable bits

(1)

If PIC16LF1516/7/8/9 (regulator disabled):

These bits are ignored. All V

CAP pin functions are disabled.

PIC16F1516/7/8/9 (regulator enabled):

0 =V

CAP functionality is enabled on RA5

1 =All V

CAP pin functions are disabled

bit 3-2 Unimplemented: Read as ‘1’

bit 1-0 WRT<1:0>: Flash Memory Self-Write Protection bits

8 kW Flash memory (

PIC16(L)F1516/7 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)F1518/9 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

Note 1: PIC16F1516/7/8/9 only.
