Timer Counter 0 – TCNT0

• Bits 2, 1, 0 – CS02, CS01, CS00: Clock Select0, Bits 2, 1 and 0
The Clock Select0 bits 2, 1 and 0 define the prescaling source of Timer/Counter0.
Table 14. Clock 0 Prescale Select
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 software control of the counting.
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.
