PWM auto-reload timer (ART)
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:
●
●
●
●
●
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.
