TCNT0 – Timer/Counter Register
OCR0A – Output Compare Register A
OCR0B – Output Compare Register B
Table 4-38.
If external pin modes are used for the Timer/Counter0, transitions on the T0 pin will clock the
counter even if the pin is configured as an output. This feature allows software control of the
counting.
The Timer/Counter Register gives direct access, both for read and write operations, to the
Timer/Counter unit 8-bit counter. Writing to the TCNT0 Register blocks (removes) the Com-
pare Match on the following timer clock. Modifying the counter (TCNT0) while the counter is
running, introduces a risk of missing a Compare Match between TCNT0 and the OCR0x
Registers.
The Output Compare Register A contains an 8-bit value that is continuously compared with
the counter value (TCNT0). A match can be used to generate an Output Compare interrupt, or
to generate a waveform output on the OC0A pin.
The Output Compare Register B contains an 8-bit value that is continuously compared with
the counter value (TCNT0). A match can be used to generate an Output Compare interrupt, or
to generate a waveform output on the OC0B pin.
