16-bit Timer/Counter

Overview
104
ATmega162(V/U/L)
The 16-bit Timer/Counter unit allows accurate program execution timing (event man-
agement), wave generation, and signal timing measurement. The main features are:
•
•
•
•
•
•
•
•
•
•
•
Note that in ATmega161 compatibility mode, only one 16-bits Timer/Counter is available
(Timer/Counter1).
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 Com-
pare 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 Figure 46. For the
actual placement of I/O pins, refer to “Pinout ATmega162” on page 2. CPU accessible
I/O Registers, including I/O bits and I/O pins, are shown in bold. The device-specific I/O
Register and bit locations are listed in the “16-bit Timer/Counter Register Description”
on page 126.
