15.4.8
To initiate a Start condition, the user sets the Start
Condition Enable bit, SEN (SSPCON2<0>). If the SDA
and SCL pins are sampled high, the Baud Rate Gener-
ator is reloaded with the contents of SSPADD<6:0>
and starts its count. If SCL and SDA are both sampled
high when the Baud Rate Generator times out (T
the SDA pin is driven low. The action of the SDA being
driven low while SCL is high is the Start condition and
causes the S bit (SSPSTAT<3>) to be set. Following
this, the Baud Rate Generator is reloaded with the
contents of SSPADD<6:0> and resumes its count.
When the Baud Rate Generator times out (T
SEN bit (SSPCON2<0>) will be automatically cleared
by hardware, the Baud Rate Generator is suspended,
leaving the SDA line held low and the Start condition is
complete.
