FOSC0
bit 11
bit 0
bit 11-4:
Unimplemented: Read as ‘0’
bit 3:
CP: Code protection bit.
1
= Code protection off
0
= Code protection on
bit 2:
WDTE: Watchdog timer enable bit
1
= WDT enabled
0
= WDT disabled
bit 1-0:
FOSC1:FOSC0: Oscillator selection bits(2)
00
= LP oscillator
01
= XT oscillator
10
= HS oscillator
11
= RC oscillator
Note 1: Refer to the PIC16C5X Programming Specifications (Literature Number DS30190) to determine how to
access the configuration word.
2: PIC16LV54A supports XT, RC and LP oscillator only.
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
1 = bit is set
0 = bit is cleared
x = bit is unknown
