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 PD4/(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 realized 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.
