Timer/Counter0 is a general purpose, single compare unit, 8-bit Timer/Counter module. The
main features are:

A simplified block diagram of the 8-bit Timer/Counter is shown in
placement of I/O pins, refer to

shown in bold. The device-specific I/O Register and bit locations are listed in the
Description” on page
Figure 14-1. 8-bit Timer/Counter Block Diagram
The Timer/Counter (TCNT0) and Output Compare Register (OCR0A) are 8-bit registers. Inter-
rupt request (abbreviated to Int.Req. in the figure) signals are all visible in the Timer Interrupt
Flag Register (TIFR0). All interrupts are individually masked with the Timer Interrupt Mask Reg-
ister (TIMSK0). TIFR0 and TIMSK0 are not shown in the figure.
The Timer/Counter can be clocked internally, via the prescaler, or by an external clock source on
the T0 pin. The Clock Select logic block controls which clock source and edge the Timer/Counter
