15.4.8
To initiate a Start condition, the user sets the Start
Enable bit, SEN (SSPxCON2<0>). If the SDAx and
SCLx pins are sampled high, the Baud Rate Generator
is reloaded with the contents of SSPxADD<6:0> and
starts its count. If SCLx and SDAx are both sampled
high when the Baud Rate Generator times out (T
the SDAx pin is driven low. The action of the SDAx
being driven low while SCLx is high is the Start condi-
tion and causes the S bit (SSPxSTAT<3>) to be set.
Following this, the Baud Rate Generator is reloaded
with the contents of SSPxADD<6:0> and resumes its
count. When the Baud Rate Generator times out

suspended, leaving the SDAx line held low and the

If the user writes the SSPxBUF when a Start sequence

If at the beginning of the Start condition,
the SDAx and SCLx pins are already sam-
pled low, or if during the Start condition, the
SCLx line is sampled low before the SDAx
line is driven low, a bus collision occurs.
