(PLLON = 0), selecting CGMVCLK requires two writes to the PLL control
register. (See
PRE1 and PRE0 — Prescaler Program Bits
The value of P is normally 0 when using a 32.768-kHz crystal as the
reference.

These read/write bits control a prescaler that selects the prescaler
power-of-two multiplier, P. (See
PLL.) PRE1 and PRE0 cannot be written when the PLLON bit is set.
Reset clears these bits.
These read/write bits control the VCO’s hardware power-of-two range
multiplier E that, in conjunction with L (See
