Unimplemented: Read as ‘1’
BOREN: Brown-out Reset Enable bit⁽²⁾
1 = BOR enabled
0 = BOR disabled
Unimplemented: Read as ‘1’
CP: FLASH Program Memory Code Protection bit
1 = Code protection off
0 = All memory locations code protected
PWRTEN: Power-up Timer Enable bit
1 = PWRT disabled
0 = PWRT enabled
WDTEN: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled
FOSC1:FOSC0: Oscillator Selection bits
11 = RC oscillator
10 = HS oscillator
01 = XT oscillator
00 = LP oscillator
Note 1: The erased (unprogrammed) value of the configuration word is 3FFFh.
2: Enabling Brown-out Reset automatically enables Power-up Timer (PWRT), regardless of
the value of bit PWRTEN. Ensure the Power-up Timer is enabled any time Brown-out
Reset is enabled.
Legend:
R = Readable bit
P = Programmable bit
- n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘1’
u = Unchanged from programmed state
