TXI

Transmit Done Interrupt Flag.

0 (NOT_SET): Read: A transmit done interrupt has not occurred. Write: Clear the transmit done interrupt (TXI).

1 (SET): Read: Transmit done interrupt detected. If the transmit is forced to abort by a NACK response, the acknowledge interrupt (ACKI) will also be set. Write: Force a transmit done interrupt.
STAI

Start Interrupt Flag.

0 (NOT_SET): Read: Start interrupt has not occurred. Write: Clear the start interrupt (STAI).

1 (SET): Read: Start or repeat start interrupt occurred. In Slave mode, a start or repeat start is detected. In Master mode, a start or repeat start has been generated.

T3I

I2C Timer Byte 3 Interrupt Flag.

0 (NOT_SET): Read: A I2C Timer Byte 3 interrupt or SCL low timeout has not occurred. Write: Clear the I2C Timer Byte 3 interrupt (T3I).

1 (SET): Read: I2C Timer Byte 3 overflow or SCL low timeout interrupt detected. Write: Force a I2C Timer Byte 3 interrupt.
