19.4.8
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

is suspended, leaving the SDAx line held low and the
Start condition is complete.

If the user writes the SSPxBUF when a Start sequence
is in progress, the WCOL bit is set and the contents of
the buffer are unchanged (the write doesn’t occur).

If at the beginning of the Start condition, the
SDAx and SCLx pins are already sampled
low, or if during the Start condition, the
SCLx line is sampled low before the SDAx
line is driven low, a bus collision occurs, the
Bus Collision Interrupt Flag, BCLxIF, is set,
the Start condition is aborted and the I
module is reset into its Idle state.
Because queueing of events is not
allowed, writing to the lower 5 bits of
SSPxCON2 is disabled until the Start
condition is complete.
