16-bit
Timer/Counter1
Overview
2512K–AVR–01/10
The 16-bit Timer/Counter unit allows accurate program execution timing (event man-
agement), wave generation, and signal timing measurement. The main features are:
•
•
•
•
•

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 47. For the
actual placement of I/O pins, refer to “Pin Configurations” 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 location are listed in the “16-bit Timer/Counter Register Description” on
page 119.
