Description

Transmission setting

Fields

SDA_FORCE_OUT

0: direct output. 1: open drain output.
SCL_FORCE_OUT

0: direct output. 1: open drain output.
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.
RX_FULL_ACK_LEVEL

This register is used to configure the ACK value that need to sent by master when the rx_fifo_cnt has reached the threshold.
MS_MODE

Set this bit to configure the module as an I2C Master. Clear this bit to configure the module as an I2C Slave.
TRANS_START

Set this bit to start sending the data in TX FIFO.
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.
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.
CLK_EN

Reserved.
ARBITRATION_EN

This is the enable bit for I2C bus arbitration function.
FSM_RST

This register is used to reset the SCL_FSM.
REF_ALWAYS_ON

This register is used to control the REF_TICK.
