Legend:
R = Readable bit
P = Programmable 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
FCKSM<1:0>:
Clock Switching and Fail-Safe Clock Monitor Selection Configuration bits
1x
= Clock switching is disabled, Fail-Safe Clock Monitor is disabled
01
= Clock switching is enabled, Fail-Safe Clock Monitor is disabled
00
= Clock switching is enabled, Fail-Safe Clock Monitor is enabled
bit 5
SOSCSEL:
Secondary Oscillator Power Selection Configuration bit
1
= Secondary oscillator is configured for high-power operation
0
= Secondary oscillator is configured for low-power operation
bit 4-3
POSCFREQ<1:0>:
Primary Oscillator Frequency Range Configuration bits
11
= Primary oscillator/external clock input frequency is greater than 8 MHz
10
= Primary oscillator/external clock input frequency is between 100 kHz and 8 MHz
01
= Primary oscillator/external clock input frequency is less than 100 kHz
00
= Reserved; do not use
bit 2
OSCIOFNC:
CLKO Enable Configuration bit
1
= CLKO output signal is active on the OSCO pin; primary oscillator must be disabled or configured
for the External Clock mode (EC) for the CLKO to be active (POSCMD<1:0> =
11
or
00
)
0
= CLKO output is disabled
bit 1-0
POSCMD<1:0>:
Primary Oscillator Configuration bits
11
= Primary Oscillator mode is disabled
10
= HS Oscillator mode is selected
01
= XT Oscillator mode is selected
00
= External Clock mode is selected
