17.4.8
To initiate a Start condition, the user sets the Start
Enable bit, SEN (SSPCON2<0>). If the SDA and SCL
pins are sampled high, the Baud Rate Generator is
reloaded with the contents of SSPADD<6:0> and starts
its count. If SCL and SDA are both sampled high when
the Baud Rate Generator times out (T
pin is driven low. The action of the SDA being driven
low while SCL is high is the Start condition and causes
the S bit (SSPSTAT<3>) to be set. Following this, the
Baud Rate Generator is reloaded with the contents of
SSPADD<6:0> and resumes its count. When the Baud
Rate Generator times out (T
(SSPCON2<0>) will be automatically cleared by
hardware. The Baud Rate Generator is suspended,
leaving the SDA line held low and the Start condition is
complete.

If the user writes the SSPBUF when a Start sequence

If, at the beginning of the Start condition, the
SDA and SCL pins are already sampled
low, or if during the Start condition, the SCL
line is sampled low before the SDA line is
driven low, a bus collision occurs. The Bus
