Implementations

impl Ssr

pub const fn ss(&self) -> u32

Synchronous binary counter. SS[31:16]: Synchronous binary counter MSB values When Binary or Mixed mode is selected (BIN = 01 or 10 or 11): SS[31:16] are the 16 MSB of the SS[31:0] free-running down-counter. When BCD mode is selected (BIN=00): SS[31:16] are forced by hardware to 0x0000. SS[15:0]: Subsecond value/synchronous binary counter LSB values When Binary mode is selected (BIN = 01 or 10 or 11): SS[15:0] are the 16 LSB of the SS[31:0] free-running down-counter. When BCD mode is selected (BIN=00): SS[15:0] is the value in the synchronous prescaler counter. The fraction of a second is given by the formula below: Second fraction = (PREDIV_S - SS) / (PREDIV_S + 1) SS can be larger than PREDIV_S only after a shift operation. In that case, the correct time/date is one second less than as indicated by TR/DR.

pub fn set_ss(&mut self, val: u32)

Synchronous binary counter. SS[31:16]: Synchronous binary counter MSB values When Binary or Mixed mode is selected (BIN = 01 or 10 or 11): SS[31:16] are the 16 MSB of the SS[31:0] free-running down-counter.

Trait Implementations

impl Clone for Ssr

fn clone(&self) -> Ssr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ssr

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

Formats the value using the given formatter.

impl Default for Ssr

fn default() -> Ssr

Returns the “default value” for a type.

impl PartialEq for Ssr

fn eq(&self, other: &Ssr) -> 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.
