This bit enables to confirm whether the I
or released and to issue start/stop conditions in master
mode. With the clocked synchronous serial format, this bit
has no meaning. With the I
when the SDA level changes from high to low under the
condition of SCL = high, assuming that the start condition
has been issued. This bit is cleared to 0 when the SDA level
changes from low to high under the condition of SCL = high,
assuming that the stop condition has been issued. Write 1 to
BBSY and 0 to SCP to issue a start condition. Follow this
procedure when also re-transmitting a start condition. Write 0
in BBSY and 0 in SCP to issue a stop condition. To issue
start/stop conditions, use the MOV instruction.
