Timer/Counters
The AT43USB320A 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 prescal-
ing timer. Both Timer/Counters can either be used as a timer with an internal clock timebase or
as a counter with an external pin connection which triggers the counting.
Timer/Counter
Prescaler
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.
