16. 16-bit Timer/Counter1
16.1
16.2
2570M–AVR–04/11
Features
Overview
The 16-bit Timer/Counter 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, 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
placement of I/O pins, refer to
isters, 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
The PRTIM1 bit in
Timer/Counter1 module.
True 16-bit Design (i.e., Allows 16-bit PWM)
Two 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
Frequency Generator
External Event Counter
Four independent interrupt Sources (TOV1, OCF1A, OCF1B, and ICF1)
