15.6.4 I
To initiate a Start condition, the user sets the Start
Enable bit, SEN, of the SSPxCON2 register. If the
SDAx and SCLx pins are sampled high, the Baud Rate
Generator is reloaded with the contents of SSPx-
ADD<7:0> and starts its count. If SCLx and SDAx are
both sampled high when the Baud Rate Generator
times out (T

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
