To initiate a START condition, the user sets the START
Condition Enable (SEN) bit (SSPCON2 register). If the
SDA and SCL pins are sampled high, the baud rate
generator
SSPADD<6:0> and starts its count. If SCL and SDA are
both sampled high when the baud rate generator times
out (T
SDA being driven low, while SCL is high, is the START
condition, and causes the S bit (SSPSTAT register) 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
automatically cleared by hardware, the baud rate gen-
erator is suspended leaving the SDA line held low and
the START condition is complete.
