Fields

I2C_SDA_FORCE_OUT

1: direct output, 0: open drain output.
I2C_SCL_FORCE_OUT

1: direct output, 0: open drain output.
I2C_SAMPLE_SCL_LEVEL

This register is used to select the sample mode. 1: sample SDA data on the SCL low level. 0: sample SDA data on the SCL high level.
I2C_RX_FULL_ACK_LEVEL

I2C_TRANS_START

Set this bit to start sending the data in txfifo.
I2C_TX_LSB_FIRST

This bit is used to control the sending mode for data needing to be sent. 1: send data from the least significant bit, 0: send data from the most significant bit.
I2C_RX_LSB_FIRST

This bit is used to control the storage mode for received data. 1: receive data from the least significant bit, 0: receive data from the most significant bit.
I2C_CLK_EN

Reserved
I2C_ARBITRATION_EN

This is the enable bit for arbitration_lost.
