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 AWeX 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 AWeX if this is used for the same timer/counter.
The hi-res extension uses the peripheral 4x clock (Clk_PER4). 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 extensions that can be enabled for timer/counters pair on PORTC. The notation of this is HIRESC.
