Overview
2490Q–AVR–06/10
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 ATmega103 compatibility mode, only one 16-bit Timer/Counter is 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 datasheet 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 (that is, TCNT1 for accessing Timer/Counter1 counter value and so on). The physical I/O
Register and bit locations for ATmega64 are listed in the
tion” on page
