Timer/Counter Clock Sources
Counter Unit
Definitions
The following definitions are used extensively throughout the section:
The Timer/Counter can be clocked by an internal synchronous or an external asynchronous
clock source. The clock source is selected by the clock select logic which is controlled by the
clock select (CS22:0) bits located in the Timer/Counter control register (TCCR2).The clock
source clk
is written to logic one, the clock source is taken from the Timer/Counter Oscillator connected to
TOSC1 and TOSC2 or directly from TOSC1. For details on asynchronous operation, see
chronous Status Register – ASSR” on page
“Timer/Counter2 Prescaler” on page
The main part of the 8-bit Timer/Counter is the programmable bi-directional counter unit.

The counter reaches the BOTTOM when it becomes zero (0x00).
The counter reaches its MAXimum when it becomes 0xFF (decimal 255).
The counter reaches the TOP when it becomes equal to the highest value in the
count sequence. The TOP value can be assigned to be the fixed value 0xFF
(MAX) or the value stored in the OCR2A Register. The assignment is depen-
dent on the mode of operation.
