Struct rp_pac::i2c::regs::IcSdaSetup

#[repr(transparent)]
pub struct IcSdaSetup(pub u32);

I2C SDA Setup Register This register controls the amount of time delay (in terms of number of ic_clk clock periods) introduced in the rising edge of SCL - relative to SDA changing - when DW_apb_i2c services a read request in a slave-transmitter operation. The relevant I2C requirement is tSU:DAT (note 4) as detailed in the I2C Bus Specification. This register must be programmed with a value equal to or greater than 2. Writes to this register succeed only when IC_ENABLE[0] = 0. Note: The length of setup time is calculated using [(IC_SDA_SETUP - 1) * (ic_clk_period)], so if the user requires 10 ic_clk periods of setup time, they should program a value of 11. The IC_SDA_SETUP register is only used by the DW_apb_i2c when operating as a slave transmitter.

Implementations

impl IcSdaSetup

pub const fn sda_setup(&self) -> u8

SDA Setup. It is recommended that if the required delay is 1000ns, then for an ic_clk frequency of 10 MHz, IC_SDA_SETUP should be programmed to a value of 11. IC_SDA_SETUP must be programmed with a minimum value of 2.

pub fn set_sda_setup(&mut self, val: u8)

SDA Setup. It is recommended that if the required delay is 1000ns, then for an ic_clk frequency of 10 MHz, IC_SDA_SETUP should be programmed to a value of 11. IC_SDA_SETUP must be programmed with a minimum value of 2.

Trait Implementations

impl Clone for IcSdaSetup

fn clone(&self) -> IcSdaSetup

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for IcSdaSetup

fn default() -> IcSdaSetup

Returns the “default value” for a type.

impl PartialEq<IcSdaSetup> for IcSdaSetup

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

This method tests for self and other values to be equal, and is used by ==.

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

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