15.2.9
To initiate a START condition, the user sets the START
condition enable bit, SEN (SSPCON2<0>). If the SDA
and SCL pins are sampled high, the baud rate genera-
tor 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
SDA 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. Follow-
ing 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
SEN bit (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.

Note:
If at the beginning of 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.

set, the START condition is aborted and
