9 Timer/Counters
9.1 Timer/Counter0

AVR515
The Timer/Counters of ATtiny48/88 have reduced functionality as compared to those
of ATmega48/88/168 and ATmega48P/88P/168P/328P.
The 8-bit Timer/Counter0 of ATtiny48/88 does not have a PWM output stage. As a
consequence, the control bits of Timer/Counter Control Register A (TCCR0A) have
been changed and the Timer/Counter Control Register B (TCCR0B) has been
removed. The Compare Match Output (COM0xx) and Waveform Generation Mode
(WGMxx) bits of TCCR0A have been replaced by Clear Timer on Compare Match
Mode (CTC0). Also, the Clock Select bits of TCCR0B have been moved to TCCR0A.
Waveform generation modes are summarised in the table below.
Table 9-1. Waveform generation modes.
See device datasheets for detailed explanations of Timer/Counter functions.
