PLL is designed for 4 MHz input frequency, but can accept 4 MHz to 48 MHz inputs using the PLL input prescaler.
The accuracy specification of the 31 kHz clock is determined by which source is providing it at a given time.
When INTSRC (OSCTUNE<7>) is ‘1’, use the INTOSC accuracy specification. When INTSRC is ‘0’, use
the INTRC accuracy specification.
