Implementations

impl Tamper

pub fn enable(&mut self)

Enable temper detection.

After enabled the TAMPER pin is dedicated for Backup Reset function. The active level on the TAMPER pin resets all data of the BKP_DATAx registers.

Ref: Section 4.4.3, the User Manual

pub fn disable(&mut self)

Disable temper detection.

After disabled, the TAMPER pin is free for GPIO functions.

pub fn set_pin_active_high(&mut self)

Set the TAMPER pin to active high. The TAMPER pin defaults to active high after reset.

Ref: Section 4.4.3, the User Manual

pub fn set_pin_active_low(&mut self)

Set the TAMPER pin to active low. The TAMPER pin defaults to active high after reset.

Ref: Section 4.4.3, the User Manual

pub fn check_event(&self) -> bool

Check the tamper event flag by reading from TEF register bit.

pub fn clear_event_bit(&mut self)

Clear the tamper interrupt flag bit by writing 1 to TER register bit.

pub fn enable_interrupt(&mut self)

Enable the tamper interrupt by setting the Tamper interrupt enable (TPIE) register bit.

pub fn disable_interrupt(&mut self)

Disable the tamper interrupt by clearing the Tamper interrupt enable (TPIE) register bit.

pub fn check_interrupt(&self) -> bool

Check the tamper interrupt flag by reading from TIF register bit.

pub fn clear_interrupt_bit(&mut self)

Clear the tamper interrupt flag bit by writing 1 to TIR register bit.
