During a Repeated Start condition, a bus collision
occurs if:
a)
b)
When the user de-asserts 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 de-
asserted and when sampled high, the SDA pin is sam-
pled. If SDA is low, a bus collision has occurred (i.e.,
another master is attempting to transmit a data ’0’). If,
however, SDA is sampled high, then the BRG is

A low level is sampled on SDA when SCL goes
from low level to high level.
SCL goes low before SDA is asserted low, indi-
cating that another master is attempting to trans-
mit a data ’1’.

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, however, SCL goes from high to low before the BRG
times out and SDA has not already been asserted, then
a bus collision occurs. In this case, another master is
attempting to transmit a data ’1’ during the Repeated
Start condition.
If, at the end of the BRG time-out, both SCL and SDA
are still high, the SDA pin is driven low, 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 com-
plete (Figure 15-38).
