To initiate a Start condition, the user sets the Start con-
dition 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
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. Following
this, the Baud Rate Generator is reloaded with the con-
tents of SSPADD<6:0> and resumes its count. When
the Baud Rate Generator times out (T
(SSPCON2<0>) will be automatically cleared by hard-
ware, the Baud Rate Generator is suspended, leaving
the SDA line held low and the Start condition is
complete.

CONDITION TIMING
If at the beginning of the Start condition,
the SDA and SCL pins are already sam-
pled 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 Collision Interrupt Flag (BCLIF) is
set, the Start condition is aborted and the
