20.1 Introduction
What?
Quick Facts
The TIMER (Timer/Counter) keeps track of
timing and counts events, generates output
waveforms and triggers timed actions in other
peripherals.
Why?
Most applications have activities that need
to be timed accurately with as little CPU
intervention and energy consumption as
possible.
How?
The flexible 16-bit TIMER can be configured
to provide PWM waveforms with optional
dead-time insertion for e.g. motor control, or
work as a frequency generator. The Timer
can also count events and control other
peripherals through the PRS, which offloads
the CPU and reduce energy consumption.
The 16-bit general purpose Timer has 3 compare/capture channels for input capture and compare/Pulse-
Width Modulation (PWM) output. TIMER0 also includes a Dead-Time Insertion module suitable for motor
control applications.
