Table 4-14.
The Stop condition provides a Timer Enable/Disable function. The prescaled modes are scaled
directly from the CK oscillator clock for Timer/Counter0 and PCK2 for Timer/Counter2. If the
external pin modes are used for Timer/Counter0, transitions on PE0/(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 Counter0 – TCNT0
Timer/Counter2 – TCNT2
These 8-bit registers contain the value of the Timer/Counters.
