To issue a start condition, write 1 to BBSY and 0 to SCP.
Also follow this procedure when retransmitting a start
condition. To issue a stop condition, write 0 to BBSY and 0
to SCP. This bit is always read as 1. Even if 1 is written to
this bit, the data is not stored.
5
SDAO 1
R
Monitors the SDA output level. When reading and the
SDAO bit is 1, the SDA pin outputs high. When reading
and the SDAO bit is 0, the SDA pin outputs low.
4

R/W
Reserved
The write value should always be 1.
3
SCLO
