Struct esp32c6::lp_i2c0::i2c_sr::R

pub struct R(_);

Register I2C_SR reader

Implementations

impl R

pub fn i2c_resp_rec(&self) -> I2C_RESP_REC_R

Bit 0 - The received ACK value in master mode or slave mode. 0: ACK, 1: NACK.

pub fn i2c_arb_lost(&self) -> I2C_ARB_LOST_R

Bit 3 - When the I2C controller loses control of SCL line, this register changes to 1.

pub fn i2c_bus_busy(&self) -> I2C_BUS_BUSY_R

Bit 4 - 1: the I2C bus is busy transferring data, 0: the I2C bus is in idle state.

pub fn i2c_rxfifo_cnt(&self) -> I2C_RXFIFO_CNT_R

Bits 8:12 - This field represents the amount of data needed to be sent.

pub fn i2c_txfifo_cnt(&self) -> I2C_TXFIFO_CNT_R

Bits 18:22 - This field stores the amount of received data in RAM.

pub fn i2c_scl_main_state_last(&self) -> I2C_SCL_MAIN_STATE_LAST_R

Bits 24:26 - This field indicates the states of the I2C module state machine. 0: Idle, 1: Address shift, 2: ACK address, 3: Rx data, 4: Tx data, 5: Send ACK, 6: Wait ACK

pub fn i2c_scl_state_last(&self) -> I2C_SCL_STATE_LAST_R

Bits 28:30 - This field indicates the states of the state machine used to produce SCL. 0: Idle, 1: Start, 2: Negative edge, 3: Low, 4: Positive edge, 5: High, 6: Stop

Methods from Deref<Target = R<I2C_SR_SPEC>>

pub fn bits(&self) -> REG::Ux

Reads raw bits from register.

Trait Implementations

impl Deref for R

type Target = R<I2C_SR_SPEC>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<R<I2C_SR_SPEC>> for R

fn from(reader: R<I2C_SR_SPEC>) -> Self

Converts to this type from the input type.
