Enum AotClockSource 

pub enum AotClockSource {
    Xosc(FractionalFrequency),
    Lposc(FractionalFrequency),
    GpioLpOsc(FractionalFrequency),
    Gpio1kHz,
    Gpio1Hz,
}

Specify which clock source the POWMAN Always-On-Timer is clocked from.

Variants

Xosc(FractionalFrequency)

On-Chip Crystal Oscillator (XOSC).

When the chip core is powered, the tick source can be switched the on-chip crystal oscillator for greater precision.

Lposc(FractionalFrequency)

On-Chip Low-Power Oscillator (LPOSC).

The LPOSC frequency is not precise and may vary with voltage and temperature

GpioLpOsc(FractionalFrequency)

External GPIO pin input to the Low-Power Oscillator (LPOSC).

Uses the pin provided when the POWMAN driver was constructed.

Gpio1kHz

External 1 kHz GPIO pin.

Uses the pin provided when the POWMAN driver was constructed.

Gpio1Hz

External 1 Hz GPIO pin

Uses the pin provided when the POWMAN driver was constructed.

Implementations

impl AotClockSource

pub const fn new_xosc(freq: FractionalFrequency) -> AotClockSource

Create a clock source, using the XOSC running at the given frequency.

pub const fn new_lposc( freq: FractionalFrequency, ) -> Result<AotClockSource, ClockSourceError>

Create a clock source, using the LPOSC running at the given frequency.

Gives an error if the frequency is above 256 kHz.

Trait Implementations

impl Clone for AotClockSource

fn clone(&self) -> AotClockSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AotClockSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for AotClockSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for AotClockSource

fn eq(&self, other: &AotClockSource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
