"Low" level and Master B outputs the "High" level.
When the SCL line goes high at the point b, the slave device reads the SDA line data, i.e., data transmitted
by Master A. At this time, data transmitted by Master B becomes invalid.
fect the data transfer initiated by another master. If two or more masters have transmitted exactly the same
first data word, the arbitration procedure continues with the second data word.
If there is a difference between these two values, Arbitration Lost occurs and SBIxSR<AL> is set to "1".
ceiver.Therefore, the serial bus interface circuit stops the clock output during data transfer after <AL> is set
to "1".
Up until the point a, Master A and Master B output the same data. At the point a, Master A outputs the
Then Master A pulls the SDA bus line to the "Low" level because the line has the wired-AND connection.
This condition of Master B is called "Arbitration Lost". Master B releases its SDA pin, so that it does not af-
A master compares the SDA bus line level and the internal SDA output level at the rising of the SCL line.
When <AL> is set to "1", SBIxSR<MST, TRX> are cleared to "0", causing the SBI to operate as a slave re-
<AL> is cleared to "0" when data is written to or read from SBIxDBR or data is written to SBIxCR2.
