The mode of operation is defined by the Timer/Counter Width (TCWn), Input Capture Enable
(ICENn) and the Waveform Generation Mode (WGMn0)bits in
Control Register A” on page
In the normal mode, the counter (TCNTnL) is incrementing until it overruns when it passes its
maximum 8-bit value (MAX = 0xFF) and then restarts from the bottom (0x00), see
page 80
the TCNTnL becomes zero. The TOVn Flag in this case behaves like a ninth bit, except that it is
only set, not cleared. However, combined with the timer overflow interrupt that automatically
clears the TOVn Flag, the timer resolution can be increased by software. There are no special
cases to consider in the Normal 8-bit mode, a new counter value can be written anytime. The
Output Compare Unit can be used to generate interrupts at some given time.
In Clear Timer on Compare or CTC mode, the OCRnA Register is used to manipulate the
counter resolution, see
cleared to zero when the counter value (TCNTn) matches the OCRnA. The OCRnA defines the
top value for the counter, hence also its resolution. This mode allows greater control of the Com-
pare Match output frequency. It also simplifies the operation of counting external events.
The timing diagram for the CTC mode is shown in
(TCNTn) increases until a Compare Match occurs between TCNTn and OCRnA, and then
counter (TCNTn) is cleared.
