13.5.11 Slave Address Match Detection Monitor
When the SBI operates as a slave device in the address recognition mode (SBII2CAR<ALS>="0"),
SBISR<AAS> is set to "1" on receiving the general-call address or the slave address that matches the value
specified at SBII2CAR.
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 SBIDBR.
13.5.12 General-call Detection Monitor
When the SBI operates as a slave device, SBISR<ADO> is set to "1" when it receives the general-call ad-
dress; i.e., the eight bits following the start condition are all zeros.
<ADO> is cleared to "0" when the start or stop condition is detected on the bus.
13.5.13 Last Received Bit Monitor
SBISR<LRB> is set to the SDA line value that was read at the rising of the SCL line.
In the acknowledgment mode, reading SBISR<LRB> immediately after generation of the INTSBI inter-
rupt request causes ACK signal to be read.
13.5.14 Data Buffer Register (SBIDBR)
Reading or writing SBIDBR initiates reading received data or writing transmitted data.
When the SBI is acting as a master, setting a slave address and a direction bit to this register generates the
start condition.
