SPLLERR
System PLL Clock Error
This flag is reset on Chip POR only, software can also clear this flag by writing a logic one
NOTE: The LOL Flag is set when the PLL reference is out of range (Dunl in datasheet) and is constantly
modulated such that 3 consecutive un-locked samples of the reference clock are generated.
0 System PLL Clock Monitor is disabled or has not detected an error
1 System PLL Clock Monitor is enabled and detected an error. System PLL Clock Error flag will not set
when System OSC is selected as its source and SOSCERR has set.
25
SPLLSEL
System PLL Selected
0 System PLL is not the system clock source
1 System PLL is the system clock source
