To initiate a Start condition, the user sets the Start
Enable bit, SEN bit of the SSPxCON2 register. If the
SDAx and SCLx pins are sampled high, the Baud Rate
Generator
SSPxADD<7:0> and starts its count. If SCLx and
SDAx are both sampled high when the Baud Rate
Generator times out (T
low. The action of the SDAx being driven low while
SCLx is high is the Start condition and causes the S bit
of the SSPxSTAT1 register to be set. Following this,
the Baud Rate Generator is reloaded with the contents
of SSPxADD<7:0> and resumes its count. When the
Baud Rate Generator times out (T
the SSPxCON2 register will be automatically cleared
