internal clock source, selected by the Clock Select bits (CS02:0). When no clock source is
selected (CS02:0 = 0) the timer is stopped. However, the TCNT0 value can be accessed by the
CPU, regardless of whether clk
T0 is present or not. A CPU write overrides (has priority over) all
counter clear or count operations. The Timer/Counter Overflow Flag (TOV0) is set when the
counter reaches the maximum value and it can be used for generating a CPU interrupt.

Input Capture Unit
The Timer/Counter incorporates an Input Capture unit that can capture external events and give
them a time-stamp indicating time of occurrence. The external signal indicating an event, or mul-
tiple events, can be applied via the ICP0 pin or alternatively, via the analog-comparator unit. The
time-stamps can then be used to calculate frequency, duty-cycle, and other features of the sig-
nal applied. Alternatively the time-stamps can be used for creating a log of the events.
The Input Capture unit is illustrated by the block diagram shown in Figure 11-4. The elements of
the block diagram that are not directly a part of the Input Capture unit are gray shaded.
Figure 11-4.
Input Capture Unit Block Diagram
The Output Compare Register OCR0A is a dual-purpose register that is also used as an 8-bit
Input Capture Register ICR0. In 16-bit Input Capture mode the Output Compare Register
OCR0B serves as the high byte of the Input Capture Register ICR0. In 8-bit Input Capture mode
the Output Compare Register OCR0B is free to be used as a normal Output Compare Register,
but in 16-bit Input Capture mode the Output Compare Unit cannot be used as there are no free
Output Compare Register(s). Even though the Input Capture register is called ICR0 in this sec-
tion, it is refering to the Output Compare Register(s).
When a change of the logic level (an event) occurs on the Input Capture pin (ICP0), alternatively
on the Analog Comparator output (ACO), and this change confirms to the setting of the edge
detector, a capture will be triggered. When a capture is triggered, the value of the counter
(TCNT0) is written to the Input Capture Register (ICR0). The Input Capture Flag (ICF0) is set at
ICF0 (Int.Req.)
