6.5 Timers/counters 0 and 1
The two 16-bit Timer/Counter registers: Timer 0 and Timer 1 can be configured to operate
either as timers or event counters (see Table 26 and Table 27).
In the ‘Timer’ function, the register is incremented every machine cycle. Thus, one can
think of it as counting machine cycles. Since a machine cycle consists of six oscillator
periods, the count rate is 16 of the oscillator frequency.
