The AT43USB325 provides two general-purpose Timer/Counters - one 8-bit T/C and one 16-bit
T/C. The Timer/Counters have individual prescaling selection from the same 10-bit prescaling
timer. Both Timer/Counters can either be used as a timer with an internal clock time base or as a
counter with an external pin connection which triggers the counting.
The four different prescaled selections are: CK/8, CK/64, CK/256 and CK/1024 where CK is the
oscillator clock. For the two Timer/Counters, added selections as CK, external source and stop,
can be selected as clock sources.
