Timer/Counter2 is a general purpose, single compare unit, 8-bit Timer/Counter module. A simpli-
fied block diagram of the 8-bit Timer/Counter is shown in
of I/O pins, refer to
on page
device-specific I/O Register and bit locations are listed in the

Figure 17-1. 8-bit Timer/Counter Block Diagram
The Timer/Counter (TCNT2) and Output Compare Register (OCR2A) are 8-bit registers. Inter-
rupt request (shorten as Int.Req.) signals are all visible in the Timer Interrupt Flag Register
Single Compare Unit Counter
Clear Timer on Compare Match (Auto Reload)
Glitch-free, Phase Correct Pulse Width Modulator (PWM)
Frequency Generator
10-bit Clock Prescaler
Overflow and Compare Match Interrupt Sources (TOV2 and OCF2A)
Allows Clocking from External 32kHz Watch Crystal Independent of the I/O Clock
