Features
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 A1 devices have four Hi-Res Extensions that each can be enabled for each
Timer/Counters pair on PORTC, PORTD, PORTE and PORTF. The notation of these peripher-
als are HIRESC, HIRESD, HIRESE and HIRESF, respectively.
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
