I2C_I3C_DIS

EN_SPI_READ

SDA_PU_EN

CS_PU_DIS

I2C_I3C_DIS

Disable I²C and I3C digital interfaces. Default value: 0

(0: enable I²C and I3C digital interfaces; 1: disable I²C and I3C digital interfaces)

EN_SPI_READ

Enable SPI read mode. This bit must be set to 1 before using the 3-wire SPI interface. Default value: 0

(0: disable SPI read for 3-wire SPI; 1: enable SPI read for 3-wire SPI)

SDA_PU_EN

Enable pull-up on the SDA pin. Default value: 0

(0: SDA pin pull-up disconnected; 1: SDA pin with pull-up)

CS_PU_DIS

Disable pull-up on CS pin. Default value: 0

(0: CS pin with internal pull-up; 1: CS pin pull-up disconnected)
