if I could ask another noobie question: I have a pin configured like this:
```
        let mut leg_a = gpioc.pc14.into_pull_up_input();
        leg_a.make_interrupt_source(&mut syscfg);
        leg_a.enable_interrupt(&mut perfs.EXTI);
        leg_a.trigger_on_edge(&mut perfs.EXTI, Edge::FALLING);
```
I have it connected to a botton that goes from the pin to ground.
I then have an rtic task declare like this:
```
    #[task(binds = EXTI15_10,
        resources = [leg_a])]
    fn rotate(c : rotate::Context)
    {
        defmt::info!("rotate");
        c.resources.leg_a.clear_interrupt_pending_bit(); 
    }
```
and I constantly get rotate in the log output. I'm doing something dumb, I just don't know it yet.
any ideas?
