bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7

Unimplemented:

Read as ‘0’

bit 6-3

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)

bit 1-0

SCS<1:0>:

System Clock Select bits

= Internal oscillator block

= Secondary oscillator

= Clock determined by FOSC<2:0> in Configuration Word 1.

Note 1:

Duplicate frequency derived from HFINTOSC.
