After the SDA pin has been de-asserted and
allowed to float high, SDA is sampled low after
the BRG has timed out.
After the SCL pin is de-asserted, SCL is
sampled low before SDA goes high.

The Stop condition begins with SDA asserted low.
When SDA is sampled low, the SCL pin is allowed to
float. When the pin is sampled high (clock arbitration),
the Baud Rate Generator is loaded with SSPADD<6:0>
and counts down to 0. After the BRG times out, SDA is
sampled. If SDA is sampled low, a bus collision has
occurred. This is due to another master attempting to
drive a data ‘0’ (Figure 13-26). If the SCL pin is sam-
pled low before SDA is allowed to float high, a bus col-
lision occurs. This is another case of another master
attempting to drive a data ‘0’ (Figure 13-27).
SCL goes low before SDA goes high,
