bit 2-0 FOSC<2:0>: Oscillator Selection bits
111 = RC oscillator: CLKOUT function on RA6/OSC2/CLKOUT pin, RC on RA7/OSC1/CLKIN
110 = RCIO oscillator: I/O function on RA6/OSC2/CLKOUT pin, RC on RA7/OSC1/CLKIN
101 = INTOSC oscillator: CLKOUT function on RA6/OSC2/CLKOUT pin, I/O function on RA7/OSC1/CLKIN
100 = INTOSCIO oscillator: I/O function on RA6/OSC2/CLKOUT pin, I/O function on RA7/OSC1/CLKIN
011 = EC: I/O function on RA6/OSC2/CLKOUT pin, CLKIN on RA7/OSC1/CLKIN
010 = HS oscillator: High-speed crystal/resonator on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN
001 = XT oscillator: Crystal/resonator on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN
000 = LP oscillator: Low-power crystal on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN
REGISTER 8-1: CONFIG1: CONFIGURATION WORD REGISTER 1 (CONTINUED)
Note 1: Enabling Brown-out Reset does not automatically enable Power-up Timer.
2: The entire program memory will be erased when the code protection is turned off.
3: When MCLR
is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.
4: MPLAB
®
IDE masks unimplemented Configuration bits to ‘0’.

Legend: P = Programmable bit
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
bit 13-6 Unimplemented: Read as ‘1’
bit 5-4 VCAPEN<1:0>: Voltage Regulator Capacitor Enable bits
For the
PIC16LF72X:
These bits are ignored. All V
CAP pin functions are disabled.
For the
PIC16F72X:
00 =V
CAP functionality is enabled on RA0
01 =V
CAP functionality is enabled on RA5
10 =V
CAP functionality is enabled on RA6
11 = All V
CAP functions are disabled (not recommended)
bit 3-0 Unimplemented: Read as ‘1’
Note 1: MPLAB
