Features
Overview
•
•
•
The high-resolution (hi-res) extension can be used to increase the resolution of the waveform
generation output from a timer/counter by four or eight. It can be used for a timer/counter doing
frequency, single-slope PWM, or dual-slope PWM generation. It can also be used with the
AWeX if this is used for the same timer/counter.
The hi-res extension uses the peripheral 4x clock (Clk
be configured so the peripheral 4x clock frequency is four times higher than the peripheral and
CPU clock frequency when the hi-res extension is enabled.
Atmel AVR XMEGA B3 devices have one Hi-Res Extension that can be enabled for the
timer/counters pair on PORTC. The notation of this is HIRESC.
Increases waveform generator resolution up to 8x (3 bits)
Supports frequency, single-slope PWM, and dual-slope PWM generation
Supports the AWeX when this is used for the same timer/counter
