LL_I2C_InitTypeDef struct

Specifies the peripheral mode. This parameter can be a value of I2C_LL_EC_PERIPHERAL_MODE This feature can be modified afterwards using unitary function LL_I2C_SetMode().

Specifies the clock frequency. This parameter must be set to a value lower than 400kHz (in Hz) This feature can be modified afterwards using unitary function LL_I2C_SetClockPeriod() or LL_I2C_SetDutyCycle() or LL_I2C_SetClockSpeedMode() or LL_I2C_ConfigSpeed().

Specifies the I2C fast mode duty cycle. This parameter can be a value of I2C_LL_EC_DUTYCYCLE This feature can be modified afterwards using unitary function LL_I2C_SetDutyCycle().

Enables or disables analog noise filter. This parameter can be a value of I2C_LL_EC_ANALOGFILTER_SELECTION This feature can be modified afterwards using unitary functions LL_I2C_EnableAnalogFilter() or LL_I2C_DisableAnalogFilter().

Configures the digital noise filter. This parameter can be a number between Min_Data = 0x00 and Max_Data = 0x0F This feature can be modified afterwards using unitary function LL_I2C_SetDigitalFilter().

Specifies the device own address 1. This parameter must be a value between Min_Data = 0x00 and Max_Data = 0x3FF This feature can be modified afterwards using unitary function LL_I2C_SetOwnAddress1().

Specifies the ACKnowledge or Non ACKnowledge condition after the address receive match code or next received byte. This parameter can be a value of I2C_LL_EC_I2C_ACKNOWLEDGE This feature can be modified afterwards using unitary function LL_I2C_AcknowledgeNextData().

Specifies the device own address 1 size (7-bit or 10-bit). This parameter can be a value of I2C_LL_EC_OWNADDRESS1 This feature can be modified afterwards using unitary function LL_I2C_SetOwnAddress1().
