pub struct W(_);

Register CTR writer

Implementations

impl W

pub fn sda_force_out(
    &mut self
) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 0>

Bit 0 - 1: normally ouput sda data 0: exchange the function of sda_o and sda_oe (sda_o is the original internal output sda signal sda_oe is the enable bit for the internal output sda signal)

pub fn scl_force_out(
    &mut self
) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 1>

Bit 1 - 1: normally ouput scl clock 0: exchange the function of scl_o and scl_oe (scl_o is the original internal output scl signal scl_oe is the enable bit for the internal output scl signal)

pub fn sample_scl_level(
    &mut self
) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 2>

Bit 2 - Set this bit to sample data in SCL low level. clear this bit to sample data in SCL high level.

pub fn ms_mode(&mut self) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 4>

Bit 4 - Set this bit to configure the module as i2c master clear this bit to configure the module as i2c slave.

pub fn trans_start(&mut self) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 5>

Bit 5 - Set this bit to start sending data in txfifo.

pub fn tx_lsb_first(&mut self) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 6>

Bit 6 - This bit is used to control the sending mode for data need to be send. 1: receive data from most significant bit 0: receive data from least significant bit

pub fn rx_lsb_first(&mut self) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 7>

Bit 7 - This bit is used to control the storage mode for received datas. 1: receive data from most significant bit 0: receive data from least significant bit

pub fn clk_en(&mut self) -> BitWriterRaw<'_, u32, CTR_SPEC, bool, BitM, 8>

Bit 8 - This is the clock gating control bit for reading or writing registers.

pub unsafe fn bits(&mut self, bits: u32) -> &mut W

Writes raw bits to the register.

Methods from Deref<Target = W<CTR_SPEC>>

pub unsafe fn bits(&mut self, bits: <REG as RegisterSpec>::Ux) -> &mut W<REG>

Writes raw bits to the register.

Safety

Read datasheet or reference manual to find what values are allowed to pass.

Trait Implementations

impl Deref for W

type Target = W<CTR_SPEC>

The resulting type after dereferencing.

fn deref(&self) -> &<W as Deref>::Target

Dereferences the value.

impl DerefMut for W

fn deref_mut(&mut self) -> &mut <W as Deref>::Target

Mutably dereferences the value.

impl From<W<CTR_SPEC>> for W

fn from(writer: W<CTR_SPEC>) -> W

Converts to this type from the input type.
