10.2 PWM AUTO-RELOAD TIMER (ART)
10.2.1 Introduction
The Pulse Width Modulated Auto-Reload Timer
on-chip peripheral consists of an 8-bit auto reload
counter with compare/capture capabilities and of a
7-bit prescaler clock source.
These resources allow five possible operating
modes:
– Generation of up to 2 independent PWM signals
– Output compare and Time base interrupt

– Up to two input capture functions
– External event detector
– Up to two external interrupt sources
The three first modes can be used together with a
single counter frequency.
The timer can be used to wake up the MCU from
WAIT and HALT modes.
