Overview
The 16-bit Timer/Counter 1 unit allows accurate program execution timing (event management),
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 (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
including I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit loca-
tions are listed in the

True 16-bit Design (i.e., Allows 16-bit PWM)
Three independent Output Compare Units
Double Buffered Output Compare Registers
One Input Capture Unit
Input Capture Noise Canceler
Clear Timer on Compare Match (Auto Reload)
Glitch-free, Phase Correct Pulse Width Modulator (PWM)
Variable PWM Period

External Event Counter
Five independent interrupt sources (TOV1, OCF1A, OCF1B, OCF1C, ICF1)
must be written to zero to enable Timer/Counter1 module.
