Reset state depends on the state of the IESO Configuration bit (CONFIG1H<7>).
Modifying these bits will cause an immediate clock frequency switch if the internal oscillator is providing
the device clocks.
Source selected by the INTSRC bit (OSCTUNE<7>).
Modifying these bits will cause an immediate clock source switch.
INTSRC = OSCTUNE<7> and MFIOSEL = OSCCON2<0>.
