Type Definitions

RXFIFO_END_ADDR_R

Field RXFIFO_END_ADDR reader - This is the offset address of the last received data, as described in I2C_NONFIFO_RX_THRES. This value refreshes when an I2C_RXFIFO_UDF_INT or I2C_TRANS_COMPLETE_INT interrupt is generated.

RXFIFO_START_ADDR_R

Field RXFIFO_START_ADDR reader - This is the offset address of the last received data, as described in I2C_NONFIFO_RX_THRES.

RX_UPDATE_W

Field RX_UPDATE writer - Write 0 or 1 to I2C_RX_UPDATE to update the value of I2C_RXFIFO_END_ADDR and I2C_RXFIFO_START_ADDR.

SLAVE_RW_POINT_R

Field SLAVE_RW_POINT reader - The received data in I2C slave mode.

TXFIFO_END_ADDR_R

Field TXFIFO_END_ADDR reader - This is the offset address of the last sent data, as described in I2C_NONFIFO_TX_THRES. The value refreshes when an I2C_TXFIFO_OVF_INT or I2C_TRANS_COMPLETE_INT interrupt is generated.

TXFIFO_START_ADDR_R

Field TXFIFO_START_ADDR reader - This is the offset address of the first sent data, as described in I2C_NONFIFO_TX_THRES.

TX_UPDATE_W

Field TX_UPDATE writer - Write 0 or 1 to I2C_TX_UPDATE to update the value of I2C_TXFIFO_END_ADDR and I2C_TXFIFO_START_ADDR.
