Overview

The 16-bit Timer/Counter unit allows accurate program execution timing (event management),

wave generation, and signal timing measurement. Most register and bit references in this sec-

tion are written in general form. A lower case "n" replaces the Timer/Counter number, and a

lower case "x" replaces the output compare unit. 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 16-1. For the actual

placement of I/O pins, refer to Figure 1-1 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 “Register Description” on page 112.
