XMEGA A4
18. Hi-Res - High Resolution Extension
18.1 Features
• Increases Waveform Generator resolution by 2-bits (4x)
• Supports Frequency, single- and dual-slope PWM operation
• Supports the AWEX when this is enabled and used for the same Timer/Counter
18.2 Overview
The Hi-Resolution (Hi-Res) Extension is able to increase the resolution of the waveform genera-
tion output by a factor of 4. When enabled for a Timer/Counter, the Fast Peripheral clock running
at four times the CPU clock speed will be as input to the Timer/Counter.
The High Resolution Extension can also be used when an AWEX is enabled and used with a
Timer/Counter.
XMEGA A4 devices have three Hi-Res Extensions that each can be enabled for each
Timer/Counters pair on PORTC, PORTD and PORTE. The notation of these are HIRESC,
HIRESD and HIRESE, respectively.
