Overview
The 16-bit Timer/Counter unit allows accurate program execution timing (event management), wave generation,
and signal timing measurement.
and signal timing measurement.
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.
