18.4.17.2
During a Repeated Start condition, a bus collision
occurs if:
a)
b)
When the user deasserts SDA and the pin is allowed to
float high, the BRG is loaded with SSPADD<6:0> and
counts down to 0. The SCL pin is then deasserted and
when sampled high, the SDA pin is sampled.
FIGURE 18-29:
FIGURE 18-30:
DS39637D-page 228
A low level is sampled on SDA when SCL goes
from a low level to a high level.
SCL goes low before SDA is asserted low, indi-
cating that another master is attempting to
transmit a data ‘1’.

Sample SDA when SCL goes high.
If SDA = 0, set BCLIF and release SDA and SCL.
If SDA is low, a bus collision has occurred (i.e., another
master is attempting to transmit a data ‘0’, see
Figure 18-29). If SDA is sampled high, the BRG is
reloaded and begins counting. If SDA goes from high-to-
low before the BRG times out, no bus collision occurs
because no two masters can assert SDA at exactly the
same time.
If SCL goes from high-to-low before the BRG times out,
and SDA has not already been asserted, a bus collision
occurs. In this case, another master is attempting to
transmit a data ‘1’ during the Repeated Start condition,
see Figure 18-30.
If, at the end of the BRG time-out, both SCL and SDA
are still high, the SDA pin is driven low and the BRG is
reloaded and begins counting. At the end of the count
regardless of the status of the SCL pin, the SCL pin is
driven low and the Repeated Start condition is
complete.
