Struct Tamp 

pub struct Tamp<'d> { /* private fields */ }

Tamper detection driver.

Implementations

impl<'d> Tamp<'d>

pub fn new( _peri: Peri<'d, TAMP>, _irq: impl Binding<TAMP, InterruptHandler> + 'd, ) -> Self

Create a new tamper detection driver.

pub fn configure_external_channel( &mut self, channel: u8, pin: Peri<'d, impl Pin>, config: ExternalTamperConfig, ) -> ExternalTamperPin<'d>

Enable and configure an external tamper channel, binding it to pin.

channel is the 0-based tamper channel index (TAMP1 = 0, TAMP2 = 1, …). It must match the silicon pin mapping documented in your chip’s reference manual/datasheet; this is not checked against the pin passed in.

pub fn enable_internal_tamper(&mut self, tamper: InternalTamper)

Enable an internal tamper condition.

pub fn disable_internal_tamper(&mut self, tamper: InternalTamper)

Disable an internal tamper condition.

pub async fn wait_for_tamper(&mut self) -> TamperStatus

Wait for a tamper detection event.

The status returned reflects the raw, latched SR flags at the time of return. Once handled, call Self::clear_tamper_flags() with the returned status to clear it and resume monitoring those channels — until then, their interrupt is left disabled (they won’t wake this future again, but the flag itself stays latched).

pub fn tamper_status(&self) -> TamperStatus

Read the current, raw tamper detection status (SR).

pub fn clear_tamper_flags(&mut self, status: TamperStatus)

Clear the given tamper flags in SCR, and re-enable the interrupt (IER) for any of them that are still enabled in CR1.

pub fn read_backup_register(&self, register: usize) -> Option<u32>

Read a backup register (BKPRn). Returns None if register is out of range.

pub fn write_backup_register(&mut self, register: usize, value: u32)

Write a backup register (BKPRn). Silently does nothing if register is out of range.

pub fn monotonic_counter(&self) -> u32

Read the monotonic tamper counter. It increments by one on every access performed internally on a read, so consecutive calls return increasing values.

Not available on G0/G4, which don’t have this register — this method doesn’t exist on those chips.
