TCNT0 – Timer/Counter0 Register
OCR0A – Output Compare Register A
ASSR – Asynchronous Status Register
The three Clock Select bits select the clock source to be used by the Timer/Counter, see
Table
Table 10-5.
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
Register.
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.
• Bit 7 – Res: Reserved Bit
This bit is reserved in the ATtiny87/167 and will always read as zero.
• Bit 6 – EXCLK: Enable External Clock Input
When EXCLK is written to one, and asynchronous clock is selected, the external clock input
buffer is enabled and an external clock can be input on XTAL1 pin instead of an external crys-
tal. Writing to EXCLK should be done before asynchronous operation is selected. Note that
the crystal oscillator will only run when this bit is zero.
