18. Hi-Res – High Resolution Extension

18.1 Features

• Increases waveform generator resolution up to 8x (three bits)

• Supports frequency, single-slope PWM, and dual-slope PWM generation

• Supports the AWeX when this is used for the same timer/counter

18.2 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 (ClkPER4). The system clock prescalers must

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.

There is one hi-res extension that can be enabled for the timer/counter pair on PORTC. The

notation of this is HIRESC.
