The 16-bit Timer/Counter 1 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 (for this
product, only n=1 is available), 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.
A simplified block diagram of the 16-bit Timer/Counter is shown in
placement of I/O pins, see
and I/O pins, are shown in bold. The device-specific I/O Register and bit locations are listed in
