R/
This bit holds the R/W bit information received following the last address
match. This bit is only valid during the transmission.
The user may use this bit in software to determine whether transmission
or reception is in progress.
1 = Read
0 = Write
S: Start bit
This bit is cleared when the I
1 = Indicates that a start bit has been detected last. This bit is 0 on
0 = Start bit was not detected last
P: Stop bit
This bit is cleared when the I
1 = Indicates that a stop bit has been detected last.
0 = Stop bit was not detected last
D/
1 = Indicates that the last byte received was data
0 = Indicates that the last byte received was address
