can select the following count clocks by setting the PRMn2 to PRMn0 bits of prescaler mode registers
n0, n1 (PRMn0, PRMn1).
When n = 0 (TM0), T
sam
= 2T, 4T, 16T, 64T, 256T, or 1/INTWTNI cycle
When n = 1 (TM1), T
sam
= 2T, 4T, 16T, 32T, 128T, or 256T
However, when the TIn0 valid edge is selected as the count clock, T
sam
= 4T.
