FUNCTION
Read: the most recently received data bit.
Write: clears the transmit active flag.
Read: ATN = 1 if any of the flags DRDY, ARL, STR, or STP = 1.
Write: in the I

C slave mode, writing a 1 to this bit causes the I
2
C hardware to ignore the bus until it
is needed again.
Read: Data Ready flag, set when there is a rising edge on SCL.
Write: writing a 1 to this bit clears the DRDY flag.
Read: Arbitration Loss flag, set when arbitration is lost while in the transmit mode.
Write: writing a 1 to this bit clears the CARL flag.
Read: Start flag, set when a start condition is detected at a master or non-idle slave.
Write: writing a 1 to this bit clears the STR flag.
Read: Stop flag, set when a stop condition is detected at a master or non-idle slave.
Write: writing a 1 to this bit clears the STP flag.
Read: indicates whether this device is currently as bus master.
Write: writing a 1 to this bit causes a repeated start condition to be generated.
Read: undefined.
Write: writing a 1 to this bit causes a stop condition to be generated.

RDAT
FUNCTION
Read: the most recently received data bit, captured from SDA at every rising edge of SCL. Reading
I2DAT also clears DRDY and the Transmit Active state.
Write: sets the data for the next transmitted bit. Writing I2DAT also clears DRDY and sets the
Transmit Active state.
