Generating Start and Stop Conditions
When SBIxSR<BB> is “0,” writing “1” to SBIxCR2 <MST, TRX, BB, PIN> causes the SBI to
generate the start condition on the bus and output 8-bit data. <ACK> must be set to “1” in
advance.
a sequence for generating the stop condition on the bus. The contents of <MST, TRX, BB,
PIN> should not be altered until the stop condition appears on the bus.
SBIxSR<BB> can be read to check the bus state. <BB> is set to “1” when the start
condition is detected on the bus (the bus is busy), and set to “0” when the stop condition is
detected (the bus is free).
When <BB> is “1,” writing “1” to <MST, TRX, PIN> and “0” to <BB> causes the SBI to start
