The Stop condition provides a Timer Enable/Disable function. The CK down-divided

modes are scaled directly from the CK oscillator clock. If the external pin modes are

used for Timer/Counter0, transitions on PB2/(T0) will clock the counter even if the pin is

configured as an output. This feature can give the user SW control of the counting.

Timer Counter 0 – TCNT0

The Timer/Counter0 is implemented as an up-counter with read and write access. If the

Timer/Counter0 is written and a clock source is present, the Timer/Counter0 continues

counting in the timer clock cycle following the write operation.
