To initiate a Start condition, the user sets the Start
Enable bit, SEN bit of the SSPCON2 register. If the
SDA and SCL pins are sampled high, the Baud Rate
Generator
SSPADD<7:0> and starts its count. If SCL and SDA
are both sampled high when the Baud Rate Generator
times out (T
of the SDA being driven low while SCL is high is the
Start condition and causes the S bit of the SSPSTAT1
register to be set. Following this, the Baud Rate Gen-
erator is reloaded with the contents of SSPADD<7:0>
and resumes its count. When the Baud Rate Genera-
tor times out (T
