REGISTER 19-2: I2CxSTAT: I2Cx STATUS REGISTER (CONTINUED)
bit 3
S: Start bit
1 = Indicates that a Start (or Repeated Start) bit has been detected last
0 = Start bit was not detected last
Hardware is set or clear when a Start, Repeated Start or Stop is detected.
bit 2
R_W: Read/Write Information bit (when operating as I²C slave)
1 = Read – indicates data transfer is output from a slave
0 = Write – indicates data transfer is input to a slave
Hardware is set or clear after reception of an I²C device address byte.
bit 1
RBF: Receive Buffer Full Status bit
1 = Receive is complete, I2CxRCV is full
0 = Receive is not complete, I2CxRCV is empty
Hardware is set when I2CxRCV is written with a received byte. Hardware is clear when software reads
I2CxRCV.
bit 0
TBF: Transmit Buffer Full Status bit
1 = Transmit is in progress, I2CxTRN is full
0 = Transmit is complete, I2CxTRN is empty
Hardware is set when software writes to I2CxTRN. Hardware is clear at completion of a data transmission.
