BF:
Buffer full
Receive
1 = Receive complete, I

CBUF is empty
Transmit
1 = Transmit in progress, I
2
CBUF is full
0 = Transmit complete, I

CBUF is empty
UA:
Update Address (10-bit I
2
C slave mode only)
1 = Indicate that the user needs to update the address in the I

register.
0 = Address does not need to be updated
R/
W
:
Read/write bit information
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

CEN is cleared)
1 = Indicates that a start bit has been detected last. This bit is 0 on
reset.
0 = Start bit was not detected last
P:
Stop bit
This bit is cleared when the I

C module is disabled (I
2
CEN is cleared)
1 = Indicates that a stop bit has been detected last.
0 = Stop bit was not detected last
