19. Hi-Res – High Resolution Extension
19.1 Features
Increases waveform generator resolution up to 8x (three bits)
Supports frequency, single-slope PWM, and dual-slope PWM generation
Supports the WeX when this is used for the same timer/counter
19.2 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 WeX 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 timer/counters pair on PORTC. The notation of this is HIRESC.
