bit 7 bit 0

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

bit 7-6 Unimplemented: Read as ‘0’

bit 5-4 IRCF<1:0>: Internal Oscillator Frequency Select bits

11 = 8 MHz

10 = 4 MHz

01 = 1 MHz (Reset default)

00 = 31 kHz (LFINTOSC)

bit 3 Unimplemented: Read as ‘0’

bit 2 HTS: HFINTOSC Status bit

1 = HFINTOSC is stable

0 = HFINTOSC is not stable

bit 1 LTS: LFINTOSC Status bit

1 = LFINTOSC is stable

0 = LFINTOSC is not stable

bit 0 Unimplemented: Read as ‘0’
