the bus. Following the start condition, the SBI generates nine clocks from the SCL pin. The SBI outputs the
slave address and the direction bit specified at SBIxDBR with the first eight clocks, and releases the SDA
line in the ninth clock to receive an acknowledgment signal from the slave device.
In the master mode, the SBI holds the SCL line at the "Low" level while <PIN> is = "0".<TRX> changes its
value according to the transmitted direction bit at generation of the INTSBIx interrupt request, provided that
an acknowledgment signal has been returned from the slave device.

In the master mode, the following steps are required to generate the start condition and a slave address.
First, ensure that the bus is free (<BB> = "0"). Then, write "1" to SBIxCR1<ACK> to select the acknowl-
