Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets

IRCF<3:0>: Internal Oscillator Frequency Select bits
000x = 31 kHz LF
001x = 31.25 kHz
0100 = 62.5 kHz
0101 = 125 kHz
0110 = 250 kHz
0111 = 500 kHz (default upon Reset)
1000 = 125 kHz⁽¹⁾
1001 = 250 kHz⁽¹⁾
1010 = 500 kHz⁽¹⁾
1011 = 1 MHz
1100 = 2 MHz
1101 = 4 MHz
1110 = 8 MHz
1111 = 16 MHz
Unimplemented: Read as ‘0’
SCS<1:0>: System Clock Select bits
1x = Internal oscillator block
01 = Secondary oscillator
00 = Clock determined by FOSC<1:0> in Configuration Word 1.
Note 1: Duplicate frequency derived from HFINTOSC.
