Characteristics of the main system clock frequency. Set the division clock to be set by a peripheral
RH/2 or less.

5.
Selection of fsam = fPRS, fPRS/4, fPRS/256, or fPRS, fPRS/16, fPRS/64 is possible using bits 0 and 1 (PRM000,
PRM001 or PRM010, PRM011) of prescaler mode registers 00 and 01 (PRM00, PRM01). Note that
when selecting the TI000 or TI001 valid edge as the count clock, fsam = fPRS.
