REGISTER 17-2: I2CXSTAT: I2C™ STATUS REGISTER (CONTINUED)

bit 4

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.

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 set or clear when Start, Repeated Start or Stop detected.

bit 2

R_W: Read/Write Information bit (when operating as I2C slave)

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 I2C device address byte.

bit 1

RBF: Receive Buffer Full Status bit

1 = Receive complete, I2CxRCV is full

0 = Receive not complete, I2CxRCV is empty

Hardware set when I2CxRCV is written with received byte. Hardware clear when software

reads I2CxRCV.

bit 0

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.
