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)

1 = Low-voltage programming enabled

0 = High-voltage on MCLR

must be used for programming

bit 12 Unimplemented: Read as ‘1’

bit 11

LPBOR

: Low-Power BOR Enable bit

1 = Low-Power Brown-out Reset is disabled

0 = Low-Power Brown-out Reset is enabled

bit 10 BORV: Brown-Out Reset Voltage Selection bit

1 = Brown-out Reset voltage set to:

1.9V (PIC16LF1507)

2.4V (PIC16F1507), typical

0 = Brown-out Reset voltage set to 2.7V (typical)

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 8-2 Unimplemented: Read as ‘1’

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

2 k

W Flash memory:

11 = Write protection off

10 = 000h to 1FFh write-protected, 200h to 7FFh may be modified

01 = 000h to 3FFh write-protected, 400h to 7FFh may be modified

00 = 000h to 7FFh write-protected, no addresses may be modified

Note 1: The LVP bit cannot be programmed to ‘0’ when Programming mode is entered via LVP.
