A timer peripheral, tying it to the bus that clocks it.

Required Methods

fn clk(clocks: &Clocks) -> Hertz

The CK_TIMERx branch feeding this timer, taken from a frozen tree.

fn set_psc(&mut self, psc: u16)

Writes the prescaler, which reaches the counter on the next update event.

fn read_psc(&self) -> u16

Reads back the prescaler dividing the clock into counter ticks.

fn set_car(&mut self, car: u16)

Writes the auto-reload value the counter rolls over at.

fn read_car(&self) -> u16

Reads back the auto-reload value the counter rolls over at.

fn read_cnt(&self) -> u16

Reads the counter, which advances on its own while the timer runs.

fn gen_update(&mut self)

Raises an update event in software, loading the shadowed dividers.

fn set_cen(&mut self, on: bool)

Runs or halts the counter.

fn set_ups(&mut self, on: bool)

Restricts what counts as an update event to overflow/underflow — UPG no longer raises UPIF, only the counter rolling over does.

fn set_upie(&mut self, on: bool)

Lets the update event through to the NVIC. The flag is raised either way.

fn read_upie(&self) -> bool

Whether the update event reaches the NVIC.

fn read_upif(&self) -> bool

Update flag — set by hardware on every rollover, never cleared by it.

fn clear_upif(&mut self)

Clears the update flag.

unsafe fn steal(&self) -> Self

Produces a second handle to the same peripheral.

Safety

The HAL’s typestate rests on one handle meaning one configuration in flight. Keeping two handles from contradicting each other is on the caller — disjoint registers, or no reconfiguration through both.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
