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

bit 1-0

Unimplemented: Read as ‘0’

IRCF<3:0>: Internal Oscillator Frequency Select bits

1111 = 16 MHz

1110 = 8 MHz

1101 = 4 MHz

1100 = 2 MHz

1011 = 1 MHz

1010 = 500 kHz(1)

1001 = 250 kHz(1)

1000 = 125 kHz(1)

0111 = 500 kHz (default upon Reset)

0110 = 250 kHz

0101 = 125 kHz

0100 = 62.5 kHz

001x = 31.25 kHz

000x = 31 kHz LF

Unimplemented: Read as ‘0’

SCS<1:0>: System Clock Select bits

1x = Internal oscillator block

01 = Secondary oscillator

00 = Clock determined by FOSC<2:0> in Configuration Words.

Note 1: Duplicate frequency derived from HFINTOSC.
