Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-6
bit 5-4
bit 3
bit 2
bit 1
bit 0
Unimplemented: Read as ‘0’
IRCF<1:0>: Internal Oscillator Frequency Select bits
11 = 8 MHz
10 = 4 MHz
01 = 1 MHz (Reset default)
00 = 31 kHz (LFINTOSC)
Unimplemented: Read as ‘0’
HTS: HFINTOSC Status bit
1 = HFINTOSC is stable
0 = HFINTOSC is not stable
LTS: LFINTOSC Status bit
1 = LFINTOSC is stable
0 = LFINTOSC is not stable
Unimplemented: Read as ‘0’
