Features
Overview
ATmega169P Automotive
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 number. 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
