TCNT2 – Timer/Counter Register
OCR2A – Output Compare Register A
• Bit 2:0 – CS2[2:0]: Clock Select
The three Clock Select bits select the clock source to be used by the Timer/Counter, see
16-6.
Table 16-6.
The Timer/Counter Register gives direct access, both for read and write operations, to the
Timer/Counter unit 8-bit counter. Writing to the TCNT2 Register blocks (removes) the compare
match on the following timer clock. Modifying the counter (TCNT2) while the counter is running,
introduces a risk of missing a compare match between TCNT2 and the OCR2A Register.
The Output Compare Register A contains an 8-bit value that is continuously compared with the
counter value (TCNT2). A match can be used to generate an Output Compare interrupt, or to
generate a waveform output on the OC2A pin.
