D/A: Data/Address bit (when operating as I
1 = Indicates that the last byte received was data
0 = Indicates that the last byte received was device address
Hardware clear at device address match.
Hardware set by write to I2CxTRN or by reception of slave byte.
P: Stop bit
1 = Indicates that a Stop bit has been detected last
0 = Stop bit was not detected last
Hardware set or clear when Start, Repeated Start or Stop detected.
S: Start bit
1 = Indicates that a Start (or Repeated Start) bit has been detected last
0 = Start bit was not detected last
Hardware set or clear when Start, Repeated Start or Stop detected.
R/W: Read/Write bit Information (when operating as I
1 = Read – indicates data transfer is output from slave
0 = Write – indicates data transfer is input to slave
Hardware set or clear after reception of I
RBF: Receive Buffer Full Status bit
1 = Receive complete, I2CxRCV is full
0 = Receive not complete, I2CxRCV is empty
Hardware set when I2CxRCV written with received byte.
Hardware clear when software reads I2CxRCV.
TBF: Transmit Buffer Full Status bit
1 = Transmit in progress, I2CxTRN is full
0 = Transmit complete, I2CxTRN is empty
Hardware set when software writes I2CxTRN.
Hardware clear at completion of data transmission.
