Struct stm32h7::stm32h743v::i2c1::cr1::R

pub struct R { /* fields omitted */ }

Value read from the register

Methods

impl R

pub fn bits(&self) -> u32

Value of the register as raw bits

pub fn pe(&self) -> PER

Bit 0 - Peripheral enable Note: When PE=0, the I2C SCL and SDA lines are released. Internal state machines and status bits are put back to their reset value. When cleared, PE must be kept low for at least 3 APB clock cycles.

pub fn txie(&self) -> TXIER

Bit 1 - TX Interrupt enable

pub fn rxie(&self) -> RXIER

Bit 2 - RX Interrupt enable

pub fn addrie(&self) -> ADDRIER

Bit 3 - Address match Interrupt enable (slave only)

pub fn nackie(&self) -> NACKIER

Bit 4 - Not acknowledge received Interrupt enable

pub fn stopie(&self) -> STOPIER

Bit 5 - STOP detection Interrupt enable

pub fn tcie(&self) -> TCIER

Bit 6 - Transfer Complete interrupt enable Note: Any of these events will generate an interrupt: Transfer Complete (TC) Transfer Complete Reload (TCR)

pub fn errie(&self) -> ERRIER

Bit 7 - Error interrupts enable Note: Any of these errors generate an interrupt: Arbitration Loss (ARLO) Bus Error detection (BERR) Overrun/Underrun (OVR) Timeout detection (TIMEOUT) PEC error detection (PECERR) Alert pin event detection (ALERT)

pub fn dnf(&self) -> DNFR

Bits 8:11 - Digital noise filter These bits are used to configure the digital noise filter on SDA and SCL input. The digital filter will filter spikes with a length of up to DNF[3:0] * tI2CCLK ... Note: If the analog filter is also enabled, the digital filter is added to the analog filter. This filter can only be programmed when the I2C is disabled (PE = 0).

pub fn anfoff(&self) -> ANFOFFR

Bit 12 - Analog noise filter OFF Note: This bit can only be programmed when the I2C is disabled (PE = 0).

pub fn txdmaen(&self) -> TXDMAENR

Bit 14 - DMA transmission requests enable

pub fn rxdmaen(&self) -> RXDMAENR

Bit 15 - DMA reception requests enable

pub fn sbc(&self) -> SBCR

Bit 16 - Slave byte control This bit is used to enable hardware byte control in slave mode.

pub fn nostretch(&self) -> NOSTRETCHR

Bit 17 - Clock stretching disable This bit is used to disable clock stretching in slave mode. It must be kept cleared in master mode. Note: This bit can only be programmed when the I2C is disabled (PE = 0).

pub fn wupen(&self) -> WUPENR

Bit 18 - Wakeup from Stop mode enable Note: If the Wakeup from Stop mode feature is not supported, this bit is reserved and forced by hardware to 0. Please refer to Section25.3: I2C implementation. Note: WUPEN can be set only when DNF = 0000

pub fn gcen(&self) -> GCENR

Bit 19 - General call enable

pub fn smbhen(&self) -> SMBHENR

Bit 20 - SMBus Host address enable Note: If the SMBus feature is not supported, this bit is reserved and forced by hardware to 0. Please refer to Section25.3: I2C implementation.

pub fn smbden(&self) -> SMBDENR

Bit 21 - SMBus Device Default address enable Note: If the SMBus feature is not supported, this bit is reserved and forced by hardware to 0. Please refer to Section25.3: I2C implementation.

pub fn alerten(&self) -> ALERTENR

Bit 22 - SMBus alert enable Device mode (SMBHEN=0): Host mode (SMBHEN=1): Note: When ALERTEN=0, the SMBA pin can be used as a standard GPIO. If the SMBus feature is not supported, this bit is reserved and forced by hardware to 0. Please refer to Section25.3: I2C implementation.

pub fn pecen(&self) -> PECENR

Bit 23 - PEC enable Note: If the SMBus feature is not supported, this bit is reserved and forced by hardware to 0. Please refer to Section25.3: I2C implementation.
