Implementations

impl IcSsSclLcnt

pub const fn ic_ss_scl_lcnt(&self) -> u16

This register must be set before any I2C bus transaction can take place to ensure proper I/O timing. This register sets the SCL clock low period count for standard speed. For more information, refer to ‘IC_CLK Frequency Configuration’ This register can be written only when the I2C interface is disabled which corresponds to the IC_ENABLE[0] register being set to 0. Writes at other times have no effect. The minimum valid value is 8; hardware prevents values less than this being written, and if attempted, results in 8 being set. For designs with APB_DATA_WIDTH = 8, the order of programming is important to ensure the correct operation of DW_apb_i2c. The lower byte must be programmed first, and then the upper byte is programmed.

Trait Implementations

impl Clone for IcSsSclLcnt

fn clone(&self) -> IcSsSclLcnt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IcSsSclLcnt

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

Formats the value using the given formatter.

impl Default for IcSsSclLcnt

fn default() -> IcSsSclLcnt

Returns the “default value” for a type.

impl PartialEq for IcSsSclLcnt

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