A master compares the SDA bus line level and the internal SDA output level at the rising of the SCL line. If
there is a difference between these two values, Arbitration Lost occurs and SBIxSR <AL> is set to “1”.

When <AL> is set to “1,” SBIxSR <MST, TRX> are cleared to “0,” causing the SBI to operate
as a slave receiver. <AL> is cleared to “0” when data is written to or read from SBIxDBR or
data is written to SBIxCR2.
When the SBI operates as a slave device in the address recognition mode (SBIxI2CAR
<ALS> = ”0”), SBIxSR <AAS> is set to “1” on receiving the general-call address or the slave
address that matches the value specified at SBIxI2CAR. When <ALS> is “1,” <AAS> is set
to “1” when the first data word has been received. <AAS> is cleared to “0” when data is
written to or read from SBIxDBR.
When the SBI operates as a slave device, SBIxSR <AD0> is set to “1” when it receives the
general-call address; i.e., the eight bits following the start condition are all zeros. <AD0> is
cleared to “0” when the start or stop condition is detected on the bus.
SBIxSR <LRB> is set to the SDA line value that was read at the rising of the SCL line. In the
acknowledgment mode, reading SBIxSR <LRB> immediately after generation of the
INTSBIx interrupt request causes ACK signal to be read.
