10.3 PWM AUTO-RELOAD TIMER (ART)
10.3.1 Introduction
The Pulse Width Modulated Auto-Reload Timer
on-chip peripheral consists of an 8-bit auto reload
counter with compare capabilities and of a 7-bit
prescaler clock source.
These resources allow three possible operating
modes:
– Generation of up to 4 independent PWM signals
– Output compare and Time base interrupt
– External event detector

The two 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.
