The BBSY flag is set to 0 when the SDA level changes
from high to low under the condition of SCl = high,

BBSY flag is cleared to 0 when the SDA level changes
from low to high under the condition of SCl = high,
assuming that the start condition has been issued.
Writing to the BBSY flag in slave mode is disabled.
In master mode, the BBSY flag is used to issue start
and stop conditions. Write 1 to BBSY and 0 to SCP to
issue a start condition. Follow this procedure when also
re-transmitting a start condition. To issue a start/stop
condition, use the MOV instruction. The I
interface must be set in master transmit mode before
the issue of a start condition.
