Overview
2467V–AVR–02/11
The 16-bit Timer/Counter unit allows accurate program execution timing (event management),
wave generation, and signal timing measurement. The main features are:

Note that in Atmel
available (Timer/Counter1). Also note that in ATmega103 compatibility mode, the
Timer/Counter1 has two Compare Registers (Compare A and Compare B) only.
Most register and bit references in this section are written in general form. A lower case “n”
replaces the Timer/Counter number, and a lower case “x” replaces the Output Compare unit
channel. However, when using the register or bit defines in a program, the precise form must be
used i.e., TCNT1 for accessing Timer/Counter1 counter value and so on.
A simplified block diagram of the 16-bit Timer/Counter is shown in
