The Timer Counter 0 – TCNT0
The 8-bit Timer/Counter1
28
ATtiny15L
The Timer/Counter0 is implemented 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.
This module features a high-resolution and a high-accuracy usage with the lower pres-
caling opportunities. Timer/Counter1 can also be used as an accurate, high speed, 8-bit
Pulse Width Modulator (PWM) using clock speeds up to 25.6 MHz. In this mode,
Timer/Counter1 and the Output Compare Registers serve as a standalone PWM. Refer
to page 34 for a detailed description of this function. Similarly, the high-prescaling
opportunities make this unit useful for lower-speed functions or exact-timing functions
with infrequent actions.
Figure 21 shows the block diagram for Timer/Counter1.

The two Status Flags (Overflow and Compare Match) are found in the Timer/Counter
Interrupt Flag Register (TIFR). Control signals are found in the Timer/Counter Control
Register (TCCR1). The interrupt enable/disable settings are found in the Timer/Counter
Interrupt Mask Register (TIMSK).
