18.1 Features
18.2 Overview
244
ATmega128RFA1
• 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 Canceller
• Clear Timer on Compare Match (Auto Reload)
• Glitch-free, Phase Correct Pulse Width Modulator (PWM)
• Variable PWM Period
• Frequency Generator
• External Event Counter
• Numerous independent interrupt sources
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 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.
A simplified block diagram of the 16-bit Timer/Counter is shown in Figure 18-1. For the
actual placement of I/O pins, see section
accessible I/O Registers, 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 section

Register0" on page 167
The Power Reduction bits of Timer/Counter3 (PRTIM3), Timer/Counter4 bit (PRTIM4)
and Timer/Counter5 (PRTIM5) in
must be written to zero to enable the respective Timer/Counter module.
Note, note the complete Timer/Counter I/O functionality is provided for each
Timer/Counter module depending on the available I/O pins.
