FCKSM<1:0>: Clock Switching and 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
FPBDIV<1:0>: Peripheral Bus Clock Divisor Default Value bits
11 = PBCLK is SYSCLK divided by 8
10 = PBCLK is SYSCLK divided by 4
01 = PBCLK is SYSCLK divided by 2
00 = PBCLK is SYSCLK divided by 1
Reserved: Write ‘ 1 ’
OSCIOFNC: CLKO Enable Configuration bit
1 = CLKO output signal active on the OSCO pin; primary oscillator must be disabled or configured for
0 = CLKO output disabled
POSCMD<1:0>: Primary Oscillator Configuration bits
11 = Primary oscillator disabled
10 = HS oscillator mode selected
01 = XT oscillator mode selected
00 = External clock mode selected
IESO: Internal External Switchover bit
1 = Internal External Switchover mode enabled (Two-Speed Start-up enabled)
0 = Internal External Switchover mode disabled (Two-Speed Start-up disabled)
Reserved: Write ‘ 1 ’
FSOSCEN: Secondary Oscillator Enable bit
1 = Enable Secondary Oscillator
0 = Disable Secondary Oscillator
Reserved: Write ‘ 1 ’
FNOSC<2:0>: Oscillator Selection bits
000 = Fast RC Oscillator (FRC)
001 = Fast RC Oscillator with divide-by-N with PLL module (FRCDIV+PLL)
010 = Primary Oscillator (XT, HS, EC)
011 = Primary Oscillator with PLL module (XT+PLL, HS+PLL, EC+PLL)
100 = Secondary Oscillator (SOSC)
101 = Low-Power RC Oscillator (LPRC)
110 = FRCDIV16 Fast RC Oscillator with fixed divide-by-16 postscaler
111 = Fast RC Oscillator with divide-by-N (FRCDIV)
Note 1:
the External Clock mode (EC) for the CLKO to be active (POSCMD<1:0> = 11 OR 00 )
DEVCFG1: DEVICE CONFIGURATION WORD 1 (CONTINUED)
Do not disable POSC (POSCMD = 00 ) when using this oscillator source.
