WRT1

WRT0

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 = ON

Low-Voltage Programming is enabled. MCLR/VPP pin function is MCLR. MCLRE Configuration bit is

ignored.

0 = OFF

HV on MCLR/VPP must be used for programming.

bit 12-2

Unimplemented:

Read as ‘1’

bit 1-0

WRT<1:0>:

User NVM Self-Write Protection bits

11 = OFF

Write protection off

10 = BOOT

0000h to 01FFh write-protected, 0200h to 07FFh may be modified

01 = HALF

0000h to 03FFh write-protected, 0400h to 07FFh may be modified

00 = ALL

0000h to 07FFh write-protected, no addresses may be modified

WRT applies only to the self-write feature of the device; writing through ICSP™ is never protected.

Note

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