These read/write bits control a prescaler that selects the prescaler power-of-two multiplier, P. (See

These read/write bits control the VCO’s hardware power-of-two range multiplier E that, in conjunction

if the PLL is off. Therefore, PLLON cannot be cleared when BCS is set, and
BCS cannot be set when PLLON is clear. If the PLL is off (PLLON = 0),
selecting CGMVCLK requires two writes to the PLL control register. (See
4.3.8 Base Clock Selector
The value of P is normally 0 when using a 32.768-kHz crystal as the
reference.
