Cortex-M33, ultra lower power device. New out today. Let's get to it! https://www.st.com/en/microcontrollers-microprocessors/stm32u5-series.html

This code in `timer.rs`: ```rust pub fn unlisten(&mut self, event: Event) { match event { Event::TimeOut => { // Enable update event interrupt self.tim.dier.write(|w| w.uie().clear_bit()); } } } ``` should...
