Note

Selection of fsam = fX, fX/4, fX/32 is possible with bits 0 and 1 (PRM000, PRM001) of prescaler mode register

00 (PRM00) or with bits 0 and 1 (PRM010, PRM011) of prescaler mode register 01 (PRM01). Note that when

selecting TI000 (TM00) or TI001 (TM01) valid edge as the count clock, fsam = fX/16.
